Reconcile project statuses against Docker on startup, update docs and CI

- Add reconcile_project_statuses command that checks actual Docker container
  state on startup, preserving Running status for containers that are genuinely
  still running and resetting stale statuses to Stopped
- Add is_container_running helper using Docker inspect API
- Frontend calls reconciliation after Docker is confirmed available
- Update TECHNICAL.md project structure, auth modes, and file listings to
  match current codebase
- Update README.md and HOW-TO-USE.md with MCP servers, Mission Control,
  file manager, bash shells, clipboard/audio shims, and progress modal docs
- Add workflow file self-triggers to CI path filters for build-app.yml
  and build.yml
- Install Mission Control skills to ~/.claude/skills/ in entrypoint
