refactor: dual-instance setup, remove dead container code

- Make STORE_DIR, DATA_DIR, GROUPS_DIR configurable via env vars
  (NANOCLAW_STORE_DIR, NANOCLAW_DATA_DIR, NANOCLAW_GROUPS_DIR)
  for running two instances from one codebase
- Remove broken 'both' agent type sequential loop from processGroupMessages
- Delete dead code: container-runtime, mount-security, credential-proxy,
  Dockerfiles, and related config constants (~1,085 lines removed)
- Add codex instance launchd plist template
