The README referenced `deploy/install-agent.sh` and a `Containerfile` that
did not exist, so a fresh clone had no way to actually run this anywhere.
* agent: `--token-file` (and AGENT_TOKEN_FILE). The token guards hostname,
mounts, disk and GPU models and process names, and argv is world-readable
through `ps`, so a file has to win over the flag. Missing or empty token
files are fatal — falling back to "no token" would expose the host.
* deploy/install-agent.sh: creates a system user, generates the token once
(re-runs reuse it, --rotate-token for a new one), stores it 0600
root-owned, and runs the agent under ProtectSystem=strict with no
capabilities; --status and --uninstall included.
* Containerfile: two-stage, uv.lock resolved in the builder and slim Python
in the runtime. Verified with podman — the image serves /api/health as an
unprivileged user and writes its history under /var/lib/dashboards.
UV_PROJECT_ENVIRONMENT and --no-editable are what make the venv survive
being copied into the runtime stage.
* .containerignore keeps .git, .venv, data/ and .env out of the build
context.
