fix: CLI spec contradictions from codex AX audit

- Fix paths: relative to agent home dir, not hardcoded /home/agent
- Add worker/dream coordination: dream pauses worker to prevent file races
- Watch registration via .colony.toml (server reads agent config)
- Remove remaining old mentions API reference (use inbox instead)
