Conversation
Add `rootfiles tenant` (create, apply, status, list, user add, passwd, reset, gpu, image, port, volume resize, restart, logs, import, ops, sync) and an opt-in `tenant` host-prep module. Each tenant gets one container on the nvidia runtime, a size-capped volume on a loop-mounted image mounted before docker, accounts and host keys kept outside the container, temporary passwords that must be changed at first login, recreate with automatic rollback, GPUs in the shared allocation ledger under a tenant:<t> owner, limited operator delegation through one sudoers rule, and a JSONL audit log. Closes #78 Claude-Session: https://claude.ai/code/session_0177Zk7to4EYohgM59v4Fcj7
