[Config] Add coding guidelines and code-fixer agent

Major additions:
- Add CODING_GUIDELINES.md with "NO EMOJIS" rule
- Create code-fixer agent for automated violation fixes
- Add offline mode v2 hooks with local caching/queue
- Add periodic context save with invisible Task Scheduler setup
- Add agent coordination rules and database connection docs

Infrastructure:
- Update hooks: task-complete-v2, user-prompt-submit-v2
- Add periodic_save_check.py for auto-save every 5min
- Add PowerShell scripts: setup_periodic_save.ps1, update_to_invisible.ps1
- Add sync-contexts script for queue synchronization

Documentation:
- OFFLINE_MODE.md, PERIODIC_SAVE_INVISIBLE_SETUP.md
- Migration procedures and verification docs
- Fix flashing window guide

Updates:
- Update agent configs (backup, code-review, coding, database, gitea, testing)
- Update claude.md with coding guidelines reference
- Update .gitignore for new cache/queue directories

Status: Pre-automated-fixer baseline commit

+# Start Here - Next Session
+
+**Database:** 7 contexts saved and ready for recall
+**Last Updated:** 2026-01-17 19:04
+
+---
+
+## ✅ What's Complete
+
+1. **Offline Mode (v2 hooks)** - Full offline support with local caching/queuing
+2. **Centralized Architecture** - DB & API on RMM (172.16.3.30)
+3. **Periodic Context Save** - Script ready, tested working
+4. **JWT Authentication** - Token valid until 2026-02-16
+5. **Documentation** - Complete guides created
+
+---
+
+## 🚀 Quick Actions Available
+
+### Enable Automatic Periodic Saves
+
+```powershell
+powershell -ExecutionPolicy Bypass -File D:\ClaudeTools\.claude\hooks\setup_periodic_save.ps1
+```
+
+This sets up Task Scheduler to auto-save context every 5 minutes of active work.
+
+### Test Context Recall
+
+The hooks should automatically inject context when you start working. Check for:
+```
+<!-- Context Recall: Retrieved X relevant context(s) from API -->
+## 📚 Previous Context
+```
+
+### View Saved Contexts
+
+```bash
+curl -s "http://172.16.3.30:8001/api/conversation-contexts?limit=10" | python -m json.tool
+```
+
+---
+
+## 📋 Optional Next Steps
+
+### 1. Re-import Old Contexts (68 from Jupiter)
+
+If you want the old conversation history:
+- Old data is still on Jupiter (172.16.3.20) MariaDB container
+- Can be reimported from local `.jsonl` files if needed
+- Not critical - system works without them
+
+### 2. Mode Switching (Future Feature)
+
+The MSP/Dev/Normal mode switching is designed but not implemented yet. Database tables exist, just needs:
+- Slash commands (`.claude/commands/msp.md`, etc.)
+- Mode state tracking
+- Mode-specific behaviors
+
+---
+
+## 🔧 System Status
+
+**API:** http://172.16.3.30:8001 ✅
+**Database:** 172.16.3.30:3306/claudetools ✅
+**Contexts Saved:** 7 ✅
+**Hooks Version:** v2 (offline-capable) ✅
+**Periodic Save:** Tested ✅ (needs Task Scheduler setup for auto-run)
+

+
+## 📚 Key Documentation
+
+- `OFFLINE_MODE.md` - Complete offline mode documentation
+- `PERIODIC_SAVE_QUICK_START.md` - Quick guide for periodic saves
+- `DATA_MIGRATION_PROCEDURE.md` - How to migrate data (if needed)
+- `OFFLINE_MODE_COMPLETE.md` - Summary of offline implementation

+
+## 🎯 Context Will Auto-Load
+
+When you start your next session, the `user-prompt-submit` hook will automatically:
+1. Detect you're in the ClaudeTools project
+2. Query the database for relevant contexts
+3. Inject them into the conversation
+
+**You don't need to do anything - it's automatic!**
+
+---
+
+**Ready to continue work - context saved and system operational!**
