feat(cli): implement CLI entry point with auto-daemon launcher (Task 18)

- Add auto-daemon.ts: ensureDaemonRunning() checks health, reads pidfile,
  spawns daemon if needed, polls health up to 3s
- Rewrite index.ts: commander-based CLI with all subcommands (health,
  open, list, get, kill, navigate, click, type, scroll, eval, wait,
  screenshot, text, html, profiles)
- Add daemon project reference to cli tsconfig

packages/cli/tsconfig.json
