chore: Remove development files from git tracking and update .gitignore

Removed from git tracking:
- docs/ folder (all planning and implementation documentation)
- CLAUDE.md (AI assistant instructions)
- start-dev.sh and stop-dev.sh (development scripts)

Updated .gitignore to exclude:
- Documentation and planning files (docs/, CLAUDE.md)
- Development scripts and logs (*.dev.log, start-dev.sh, stop-dev.sh)
- Development environment folders (.dev/, dev-data/)
- Temporary development files (*.tmp, *.temp, .scratch/)

These files remain available locally for development but won't be committed to the repository.
