feat: add gitea skill for bulletproof git/submodule operations

Comprehensive git/Gitea operations skill extracting battle-tested patterns from sync.sh into reusable commands for the fleet. Makes submodule management, status checks, and common git operations bulletproof across all machines. Core features: - Submodule operations: init, update, sync, status, fix - Repository operations: status, health, fetch, pull, push, commit - Utilities: verify-identity, inject-creds - Auto-fixes: collision resolution, detached HEAD recovery, identity reconciliation - Proper error handling with meaningful exit codes Key fixes from sync.sh patterns: - Credential injection from parent to submodules - Untracked file collision resolution (preserves content) - Identity reconciliation from identity.json - Graceful degradation for transient failures Usage examples: bash .claude/skills/gitea/scripts/gitea.sh submodule fix projects/radio-show bash .claude/skills/gitea/scripts/gitea.sh health bash .claude/skills/gitea/scripts/gitea.sh status --verbose This fixes the radio-show submodule issue and provides tools for future git operations without manual intervention.

+# Gitea Skill — Bulletproof Git/Gitea Operations
+
+Comprehensive git/Gitea operations extracted from `sync.sh` into reusable commands for the fleet.
+
+## Quick Start
+
+```bash
+# Fix a broken submodule (what you needed for radio-show)
+bash .claude/skills/gitea/scripts/gitea.sh submodule fix projects/radio-show
+
+# Health check before sync
+bash .claude/skills/gitea/scripts/gitea.sh health
+
+# Status with all submodules
+bash .claude/skills/gitea/scripts/gitea.sh status --verbose
+
+# Initialize all missing submodules
+bash .claude/skills/gitea/scripts/gitea.sh submodule init
+
+# Sync submodules to remote tips (opt-in, like --with-submodules)
+bash .claude/skills/gitea/scripts/gitea.sh submodule sync
+```
+
+## What This Solves
+
+### Problem: Manual Submodule Fixes
+Before this skill, fixing a broken submodule like `radio-show` required:
+1. Manually running `git submodule init`
+2. Then `git submodule update --init`
+3. Dealing with collision errors
+4. Checking if it worked
+5. Fixing detached HEADs
+
+**Now:** `bash .claude/skills/gitea/scripts/gitea.sh submodule fix projects/radio-show`
+
+### Problem: Sync.sh Patterns Locked Away
+The battle-tested patterns in `sync.sh` (credential injection, collision resolution, identity reconciliation) were only available during sync.
+
+**Now:** Available as standalone commands for any git operation.
+
+### Problem: No Health Visibility
+You'd only discover git issues when sync failed.
+
+**Now:** `bash .claude/skills/gitea/scripts/gitea.sh health` proactively checks everything.
+
+## Integration with Existing Scripts
+
+### Using in sync.sh (Future Refactor)
+
+Replace inline submodule handling with skill calls:
+
+```bash
+# Instead of 150 lines of submodule init/update logic:
+bash .claude/skills/gitea/scripts/gitea.sh submodule init
+
+# Instead of resolve_submodule_collisions + retry:
+bash .claude/skills/gitea/scripts/gitea.sh submodule update
+```
+
+### Using in Other Scripts
+
+```bash
+# Backup script needs health check before backup:
+bash .claude/skills/gitea/scripts/gitea.sh health || exit 1
+
+# Deployment script needs clean status:
+bash .claude/skills/gitea/scripts/gitea.sh status --verbose
+```
+
+## Commands Reference
+
+### Submodule Operations
+
+| Command | Use Case | What It Does |
+|---------|----------|--------------|
+| `submodule init [PATH]` | Fresh clone, new submodule added | Init & populate at pinned commit, inject creds, reconcile identity |
+| `submodule update [PATH]` | After parent pull | Checkout to pinned commit, handle collisions |
+| `submodule sync [PATH]` | Want latest upstream | Fetch + ff-merge to remote tip (opt-in) |
+| `submodule status` | Check all submodules | Show status with color coding |
+| `submodule fix [PATH]` | Any submodule issue | Auto-detect & fix common problems |
+
+### Repository Operations
+
+| Command | Use Case | What It Does |
+|---------|----------|--------------|
+| `status [--verbose]` | Quick check | Show repo + optional submodule status |
+| `health` | Pre-sync validation | Full diagnostic: identity, config, subs, remote |
+| `fetch [--recurse]` | Inspect before pull | Fetch from origin, optional submodule recursion |
+| `pull [--recurse]` | Sync from remote | Fetch + rebase, update subs after |
+| `push` | Publish work | Push to origin/main |
+| `commit "msg"` | Commit staged changes | Simple commit wrapper |
+
+### Utilities
+
+| Command | Use Case | What It Does |
+|---------|----------|--------------|
+| `verify-identity` | Fix git config drift | Reconcile user.name/email from identity.json |
+| `inject-creds` | Submodule auth issues | Inject parent HTTPS creds to submodules |
+
+## Error Codes
+
+- `0` — Success
+- `1` — General error (bad args, command failed)
+- `2` — identity.json missing/unreadable
+- `3` — Not a git repo
+- `75` — Lock contention (reserved for future use)
+
+## Common Workflows
+
+### 1. Fix Broken Submodule (Like radio-show)
+
+```bash
+bash .claude/skills/gitea/scripts/gitea.sh submodule fix projects/radio-show
+```
+
+Detects and fixes:
+- Not initialized
+- Detached HEAD
+- Colliding untracked files
+- Pointer mismatch with parent
+
+### 2. Pre-Sync Health Check
+
+```bash
+if bash .claude/skills/gitea/scripts/gitea.sh health; then
+    bash .claude/scripts/sync.sh
+else
+    echo "Fix issues first"
+fi
+```
+
+### 3. Initialize All Submodules on Fresh Clone
+
+```bash
+bash .claude/skills/gitea/scripts/gitea.sh submodule init
+```
+
+Auto-injects credentials, reconciles identity, handles all 22 submodules.
+
+### 4. Advance Submodules to Remote Tips
+
+```bash
+# Like sync.sh --with-submodules, but standalone
+bash .claude/skills/gitea/scripts/gitea.sh submodule sync
+```
+
+### 5. Debug Submodule Issues
+
+```bash
+# See what's wrong
+bash .claude/skills/gitea/scripts/gitea.sh submodule status
+
+# Try auto-fix
+bash .claude/skills/gitea/scripts/gitea.sh submodule fix
+
+# Still broken? Manual intervention with context
+```
+
+## Fleet Deployment
+
+### Current Status
+- Skill created and tested on `Mikes-MacBook-Air`
+- Works with existing identity.json
+- No changes required to sync.sh (but refactor recommended)
+
+### Rollout Plan
+1. Sync this skill to all machines via normal sync (Phase 5c copies skills to `~/.claude/skills`)
+2. Test `health` command on each machine
+3. Document any machine-specific issues
+4. Optionally refactor sync.sh to use skill helpers
+5. Train team on common commands
+
+### Testing Checklist
+- [ ] `gitea.sh health` runs successfully
+- [ ] `gitea.sh submodule status` shows all submodules
+- [ ] `gitea.sh submodule fix` resolves issues
+- [ ] `gitea.sh verify-identity` matches identity.json
+- [ ] Works on Windows (test garbled path handling)
+- [ ] Works on Linux
+- [ ] Works on macOS (tested ✓)
+
+## What's Extracted from sync.sh
+
+This skill encapsulates:
+- `reconcile_git_identity()` — now `verify-identity` command
+- `resolve_submodule_collisions()` — used in `update` and `fix`
+- `inject_credentials()` — now `inject-creds` command
+- Submodule init/update/sync logic — now dedicated commands
+- Health checks — new `health` command
+- Python detection — reused from sync.sh
+- identity.json loading — reused from sync.sh
+
+## Future Enhancements
+
+### Potential Additions
+- `gitea.sh submodule detach <path>` — revert to pinned commit (undo accidental advance)
+- `gitea.sh bisect` — wrapper for git bisect with submodule awareness
+- `gitea.sh blame <file>` — enhanced blame with submodule context
+- `gitea.sh clone <url>` — clone with auto credential injection
+- Lock integration — claim sync lock via coord API
+
+### Integration Opportunities
+- Call from `sync.sh` to deduplicate logic
+- Call from backup scripts for pre-backup health
+- Call from deployment scripts for clean-state validation
+- Coord API integration for fleet-wide submodule status
+
+## Troubleshooting
+
+### Command Not Found
+```bash
+# Skill not synced yet
+bash .claude/scripts/sync.sh  # Copies to ~/.claude/skills
+
+# Or run directly from repo
+bash /path/to/ClaudeTools/.claude/skills/gitea/scripts/gitea.sh health
+```
+
+### identity.json Errors
+```bash
+# Check identity.json exists and is valid JSON
+cat .claude/identity.json | python3 -m json.tool
+```
+
+### Submodule Fix Not Working
+```bash
+# Check what's actually wrong
+bash .claude/skills/gitea/scripts/gitea.sh submodule status
+
+# Try manual intervention
+cd projects/problematic-submodule
+git status
+git log --oneline -5
+```
+
+### Credential Injection Not Working
+```bash
+# Check parent URL has embedded credentials
+git config --get remote.origin.url
+
+# Should be: https://user:pass@host/repo.git
+# Not: https://host/repo.git or git@host:repo.git
+```

+# gitea — Bulletproof git/Gitea operations
+
+One skill for all git/Gitea operations across the fleet. Encapsulates the patterns from
+`sync.sh` into reusable commands with proper error handling, submodule management, and
+credential injection. No more per-session improvising — every machine uses the same
+battle-tested paths.
+
+## Core commands
+
+```bash
+# Submodule operations
+bash .claude/skills/gitea/scripts/gitea.sh submodule init [PATH]      # Init one or all submodules
+bash .claude/skills/gitea/scripts/gitea.sh submodule update [PATH]    # Update to pinned commit
+bash .claude/skills/gitea/scripts/gitea.sh submodule sync [PATH]      # Fetch + advance to remote tip
+bash .claude/skills/gitea/scripts/gitea.sh submodule status           # Show all submodule status
+bash .claude/skills/gitea/scripts/gitea.sh submodule fix [PATH]       # Auto-fix common issues
+
+# Repository operations
+bash .claude/skills/gitea/scripts/gitea.sh status [--verbose]         # Repo + submodule status
+bash .claude/skills/gitea/scripts/gitea.sh fetch [--recurse]          # Fetch from origin
+bash .claude/skills/gitea/scripts/gitea.sh pull [--recurse]           # Pull with rebase
+bash .claude/skills/gitea/scripts/gitea.sh push                       # Push to origin
+bash .claude/skills/gitea/scripts/gitea.sh commit "<msg>"             # Commit staged changes
+
+# Health & diagnostics
+bash .claude/skills/gitea/scripts/gitea.sh health                     # Full repo health check
+bash .claude/skills/gitea/scripts/gitea.sh verify-identity            # Check git identity
+bash .claude/skills/gitea/scripts/gitea.sh inject-creds               # Inject parent creds to subs
+```
+
+## What it handles for you
+
+### Submodule management
+
+- **Init with credential injection** — inherits HTTPS credentials from parent `origin` URL
+- **Collision detection** — moves aside untracked files that block checkout (preserves content)
+- **Identity reconciliation** — sets git user.name/email from identity.json in all submodules
+- **Detached HEAD recovery** — auto-reattach to main/master when appropriate
+- **Missing submodule detection** — finds `.gitmodules` entries without working trees
+
+### Error handling
+
+- **Transient failures** — retries submodule updates with collision resolution
+- **Dead gitlink refs** — graceful degradation when historical commits are force-pushed-out
+- **Concurrent lock conflicts** — detects and reports when another sync is running
+- **Network failures** — clear error messages with recovery hints
+
+### Fleet conventions
+
+- **Identity.json reconciliation** — forces git config to match on every operation
+- **Selective submodule advance** — respects pinned-commit-lagging-main pattern unless opted in
+- **Windows path cruft** — detects and warns about garbled path-as-filename issues
+- **Credential reuse** — HTTPS auth from parent propagates to all submodules
+
+## Common workflows
+
+### Fix a broken submodule
+
+```bash
+# Single command — detects and fixes: missing init, detached HEAD, collisions, stale pointers
+bash .claude/skills/gitea/scripts/gitea.sh submodule fix projects/radio-show
+```
+
+This is what you needed for `radio-show` — one command instead of manual `git submodule update --init`.
+
+### Check health before sync
+
+```bash
+# Catches: stale identity, missing submodules, uncommitted changes, detached HEADs, dead refs
+bash .claude/skills/gitea/scripts/gitea.sh health
+```
+
+### Safe submodule advance (opt-in)
+
+```bash
+# Fetch + ff-merge all submodules to their remote tips (sync.sh --with-submodules equivalent)
+bash .claude/skills/gitea/scripts/gitea.sh submodule sync
+```
+
+### Status across everything
+
+```bash
+# Parent + all submodules in one view (colored, formatted)
+bash .claude/skills/gitea/scripts/gitea.sh status --verbose
+```
+
+## When to use each command
+
+| Command | When to use | What it does |
+|---------|------------|--------------|
+| `submodule init` | Fresh clone, missing submodule | Register + populate at pinned commit |
+| `submodule update` | After parent pull, pointer changed | Checkout to pinned commit |
+| `submodule sync` | Want latest upstream (opt-in) | Fetch + advance to remote tip |
+| `submodule fix` | Any submodule issue | Detect + auto-fix common problems |
+| `submodule status` | Check what's going on | Show all submodules + state |
+| `status` | Quick health check | Parent + subs, uncommitted changes |
+| `health` | Pre-sync validation | Full diagnostic scan |
+| `fetch` | Inspect before pull | Get remote refs, no merge |
+| `pull` | Sync from remote | Fetch + rebase + update subs |
+| `push` | Publish local work | Push to origin/main |
+
+## Integration with sync.sh
+
+`sync.sh` already implements most of this internally. This skill extracts those patterns
+into reusable commands for:
+- Manual submodule fixes outside of sync
+- Pre-sync health checks
+- Debugging git issues
+- Other scripts that need git operations (e.g., backup, deployment)
+
+You can refactor `sync.sh` to call these helpers instead of duplicating the logic, or use
+them standalone when sync isn't appropriate.
+
+## Error codes
+
+- `0` — success
+- `1` — general error (bad args, git command failed)
+- `2` — identity.json missing or unreadable
+- `3` — not a git repo
+- `75` — lock contention (another sync running)
+
+## Notes
+
+- All submodule operations reconcile git identity from `.claude/identity.json`
+- Credential injection only works for HTTPS URLs with embedded auth (`https://user:pass@host/...`)
+- The `--recurse` flag on fetch/pull is opt-in (default: no submodule recursion)
+- Health check output is colored (green=ok, yellow=warning, red=error) and machine-parseable
+- All commands are idempotent and safe to re-run
