Move troubleshooting and implementation docs to docs/

Relocate 30 non-essential .md files (investigation notes, fix summaries,
implementation details, status reports) from the project root into docs/
to reduce clutter. Core operational docs (README, quickstart guides,
configuration references) remain in the root.

+# Testing Notes
+
+## Monitor Script - Ctrl+C Fix
+
+**Issue**: Script wouldn't stop with Ctrl+C  
+**Fix**: Simplified signal handling with `os.Exit(0)` in goroutine  
+**Status**: ✅ Fixed in latest build
+
+Test with:
+```bash
+./bin/monitor-auth
+# Press Ctrl+C - should exit immediately
+```
+
+## Authentication Behavior
+
+**Initial Assumption**: Kosmi auto-creates accounts (INCORRECT)  
+**Reality**: Standard login - invalid credentials fail as expected
+
+The initial test with `email@email.com` / `password` happened to work because:
+- That account already existed
+- Or it was a test account
+- NOT because Kosmi auto-creates accounts
+
+**Actual Behavior**:
+- Valid credentials → login success
+- Invalid credentials → login failure (needs verification via monitoring)
+- Standard authentication flow
+
+## Next Steps
+
+1. **Run monitoring with real login**:
+   ```bash
+   ./bin/monitor-auth -login
+   # Log in with actual credentials
+   # Review auth-monitor.log for API format
+   ```
+
+2. **Verify auth API format**:
+   - Check POST requests to engine.kosmi.io
+   - Look for login mutation structure
+   - Verify token format and expiry
+   - Document actual API response
+
+3. **Update auth.go if needed**:
+   - Adjust GraphQL mutations to match actual API
+   - Update token parsing logic
+   - Test with real credentials
+
+4. **Test reconnection**:
+   - Run bridge with auth
+   - Simulate network failure
+   - Verify automatic reconnection
+   - Check token refresh works
