feat: complete reorganize-long-files cleanup

- Extract tool instance lifecycle endpoints (start/stop/restart/delete) from
  api/tool/tool_instances.py into new api/tool/tool_lifecycle.py.
- Register tool_lifecycle_router in main.py and api/tool/__init__.py.
- Extract inline WorkspaceDetailPage components into
  components/features/workspace/: detail header, tab bars, file/git/tools/settings
  panels. Slim page from ~446 to ~62 lines.
- Update OpenSpec reorganize-long-files tasks to reflect completed work and
  current source state; mark change completed.
- Regenerate project maps.

Quality gates: python3 -m py_compile (backend clean), npm run typecheck,
npm run lint, npm test -- --run (87 passed), pytest workspace integration
and unit tests (27 passed, 1 skipped).
