The skill/command DOCS instructed Claude to run a bare `py ...`, which is the
Windows py-launcher — absent on Linux/macOS (exit 127, hit on GURU-KALI). A blind
py->python3 swap is wrong too: python3 is a broken MS Store shim on some Windows
boxes where `py` is the correct launcher.
Fix mirrors the resolution the .sh skill scripts already do:
- New .claude/scripts/py.sh: picks the interpreter that actually RUNS —
identity.json python.command first, then py -> python3 -> python, each
validated with `-c 'import sys'` so the MS Store stub is skipped. exec's it.
- Repointed all DOC invocations (10 files, ~70 sites) from `py ...` to
`bash "$CLAUDETOOLS_ROOT/.claude/scripts/py.sh" ...` (incl. the `py -c` and
`py -` heredoc forms in checkpoint.md / mailbox.md).
- Left the .sh skill scripts untouched — they already resolve py/python/python3.
- errorlog.md: marked the GURU-KALI entry RESOLVED.
Depends on CLAUDETOOLS_ROOT (seeded by ensure-settings-env.py); py.sh also
self-resolves the repo root via git/cwd as a fallback.

Extract the per-machine concurrency lock from sync.sh into a sourceable
lib (.claude/scripts/sync-lock.sh) plus a `run <cmd>` wrapper that locks
the current repo (same lock-dir basename, so it mutually excludes with
sync.sh in the ClaudeTools repo and self-scopes in any project repo).
sync.sh now sources it (behavior identical — verified by review). /scc
routes its commit+push through the locked, rebase-safe sync.sh (and drops
the bare YYYY-MM-DD-session.md filename for the per-session-unique one).
/checkpoint now stages+commits atomically under the repo lock so a
concurrent session in a shared worktree can't be swept in. Closes the
remaining commit paths that bypassed the lock shipped in 6b0ce9a.
Remove /refresh-directives references from save, checkpoint, scc, sync
commands. Trim sync.md from 400+ lines to essentials.

Removed deprecated database context save functionality from /checkpoint:
- Deleted Part 2: Database Context Save section
- Removed API endpoint, JWT auth, and payload examples
- Updated description to focus on git operations only
- Simplified verification to git commit only
- Kept directives refresh requirement
Checkpoint command now handles git commits exclusively.
