Phase 004: remove the desktop shell, website tooling, and bundled hermes CLI

- Drop all desktop/Electron branches, scripts, and UI (title bar, pets,
  desktop bridge); LAN endpoint kind is now web/custom only
- Replace the bundled hermes CLI with user-side installation: add
  GET /api/hermes/cli-status plus a HermesMissingView onboarding guide
- Remove the version-management UI (snapshots handled by git) and prune
  dead website/mcu/claude scripts and lockfile entries
