chore: batch update - cleanup ghost commands, ccw-help index refresh, CLI session/orchestrator enhancements, skill minor fixes

- Add cleanup-ghost-commands.mjs script
- Refresh ccw-help index files (remove stale entries)
- CLI session manager: add instruction assembler and launch registry
- Frontend: orchestrator plan builder, property panel, dashboard toolbar updates
- Flow executor and type updates
- Minor fixes across multiple skills and commands
