#5766 "A root helper the agent can start, for a fixed set of maintenance
actions and nothing else", milestone 514.

The agent runs unprivileged under NoNewPrivileges, so it can't update or
reboot its host. It now leaves a request in /var/lib/steward-agent/requests,
the one path its unit lets it write; steward-maint.path starts maint.py as
root, which reads it without following links, accepts only update, reboot,
drain or undrain, deletes it, and writes the outcome to
/var/lib/steward-maint/results. The agent (1.17.0) reports each new result
state once as a `maintenance` event, re-checks pending updates when an update
finishes, and says in its metadata whether the helper is installed.

The units and the helper are served from one copy at
/plugins/host_agent/files/<name> (a fixed list), and install.sh plus the
install, provision and update playbooks all fetch them, replacing three
inline copies of the unit. Update agent installs the helper on existing
hosts; the Agent panel says under Manage agent whether it is there.

Steward handing out jobs is #5767; the cadence is #5768.

bvandeusenandClaude Opus 4.8 c95194747d feat(host-agent): collect container logs (incremental push, byte-capped) [M79 step 1]
CI / lint (push) Successful in 7s

CI / integration (push) Successful in 2m26s
CI / publish (push) Successful in 1m29s
Agent-side of Docker container-log collection (milestone 79). Each interval the
agent fetches new log lines per running container over the local Docker socket,
demuxes the multiplexed stream, and folds sample["docker_logs"] into the same
push as metrics — no inbound channel needed.

- since-cursor per container kept in rate-state; a container's first interval
  seeds from a short tail, then fetches incrementally via ?since=<cursor>
- _docker_request_raw + _demux_docker_logs + RFC3339Nano ts parsing (stdlib,
  TTY/unframed fallback); one row per (stream, ts, line)
- per-batch byte cap with a truncation marker; logs are dropped (never buffered)
  across a backoff so an outage keeps metrics but not stale logs
- docker_logs_enabled (default on) + docker_log_exclude per-host config keys
- AGENT_VERSION 1.6.0 -> 1.7.0

Server ignores the new sample key until the ingest step lands, so this commit is
CI-safe on its own.

bvandeusenandClaude Opus 4.8 a7a281cb11 feat(plugins): fold first-party plugins in-tree; bundled + external roots
First-party plugins (host_agent, http, snmp, traefik, unifi, docker) are now
tracked under plugins/ and baked into the image, so they version atomically
with core — ending the cross-repo import drift the roundtable->steward rename
exposed. History for these files is preserved in the archived Roundtable-plugins
repo.

Plugin discovery becomes multi-root: PLUGIN_DIR (single) -> PLUGIN_DIRS
(bundled first, then external) + PLUGIN_INSTALL_DIR. Bundled ships in the image;
third-party plugins still mount at runtime into the external root
(STEWARD_PLUGIN_DIR, default /data/plugins) and downloads/installs land there.
Bundled shadows external on a name collision.

- config.py: load_bootstrap returns plugin_dirs + plugin_install_dir
- app.py: iterate PLUGIN_DIRS at the migration + load sites
- migration_runner.py: discover_all_in() unions every plugin root
- plugin_manager.py: resolve_plugin_path() (pure, first-root-wins); load /
  install / hot-reload span all roots; installs target the external root
- settings/routes.py: _discover_plugins scans all roots, dedup bundled-first
- Dockerfile: COPY plugins/ ; docker-compose: drop host bind, document external
- tests/test_plugin_dirs.py: resolution, multi-root discovery, bootstrap split
