Fix CLI routing: single classifier, open-project for cold & hot start

- Add classify.ts as the single source of truth for CLI invocation
  routing (discriminated union, derives known commands from Commander)
- Remove all hardcoded command lists and duplicate path detection logic
- Simplify shell wrappers to dumb pipes (zero classification)
- Fix hot-start: use `open -n -g -a` (VS Code pattern) so second-instance
  event fires when app is already running
- Fix cold-start race: pull-based IPC (getPendingOpenProject) so renderer
  fetches the pending path after React mounts, instead of push event that
  arrived before the listener existed
- Fix asar read corruption: unpack node-entrypoint-runner.js from asar
  (Node.js v24 in Electron 41 can't parse package.json inside asar)
- Strip ELECTRON_RUN_AS_NODE from env when spawning desktop app from CLI
