fix: load agentType from DB, fix host process PATH and session resume

- Read/write agent_type column in getAllRegisteredGroups/setRegisteredGroup
  (was missing, causing all groups to fall back to claude-code)
- Strip CLAUDECODE env var to prevent nested session detection
- Add node binary path to spawned process PATH for launchd compatibility
- Clear stale container-era sessions that reference /workspace/group
