feat(phase-2): Theia container bridge via docker exec

- Dockerfile: install docker-ce-cli, run as root for socket access
- theia-exec.ts: container discovery (env > label > name), theiaExec(),
  syncToTheia() via docker cp
- agent-session-runner: execute_command → docker exec into Theia (fallback to local)
- agent-session-runner: syncToTheia() before auto-commit so "Open in Theia"
  shows agent files immediately after session completes
- server.ts: compute theiaWorkspaceSubdir from giteaRepo slug, log bridge status
  at startup
- custom_docker_run_options already set to mount /var/run/docker.sock
