feat: unified fleet CLI, Main Chat preservation policy, sidechat routing, and file transfers

- Added CHAT_POLICY.md and README.md banner enforcing sidechat-first and file-transfer-first rules.
- Added strict Main Chat block to super dm send and super dm wo with --allow-main-chat override.
- Implemented file transfer staging and metadata registry in super dm send-file and super dm files (with clean subcommand).
- Added full job lifecycle management (show, create, enable, disable, delete, run --follow) to super-cli.py and box-ctl.py.
- Audited all jobs in jobs/*.json and redirected automated dispatches away from Main Chat.
- Hardened chromebox-watchdog.sh with systemd user session environment exports and stale singleton cleanup.
- Added compose_check command choice to muse-chat-api.py.
