feat(phase-2): Theia HTTP sync via sync-server on port 3001

- theia-exec.ts: primary path is now HTTP sync (syncRepoToTheia) via
  sync-server.js running inside Theia on port 3001 — no docker socket needed
- syncRepoToTheia(giteaRepo): POST /sync → Theia git-pulls latest committed code
- isTheiaSyncAvailable(): health check before attempting sync
- docker exec path preserved for future use when socket is mounted
- agent-session-runner: use syncRepoToTheia after auto-commit
- server.ts: log both docker exec + HTTP sync status at startup
