POST /agents/:id/upgrade enqueues a self_upgrade command carrying the
target platform, the sha256 the server computed over its bundled binary,
and the server version. The agent downloads the replacement from the
existing /api/agents/download/:platform endpoint, verifies the checksum,
sanity-checks the new binary (--version), atomically swaps its own
executable, reports the command result, then re-execs via syscall.Exec —
no supervisor or restart plumbing required.
Agents stamp main.version via ldflags at image build, expose --version,
and now send version at register so node_agents.version refreshes on
re-register (older agents without the field keep their stored value).
The server rejects upgrades for offline nodes and for platforms with no
bundled binary (linux-amd64/linux-arm64 ship in the image).
Surfaces: nodes upgrade CLI, containr_nodes_upgrade MCP (confirm-gated),
node-detail page button, OpenAPI. Verified live: v0.0.3 agent upgraded
to v0.0.4 in place, re-registered with the new version; offline node
returns 409 NODE_OFFLINE.

* feat(scheduling): multi-node service placement + remote container lifecycle
services.node_id pins a service to a node agent: explicit id, "auto"
(least-loaded online node), or "local"/empty for the local Docker host.
- DeploymentEngine gains a NodeRunner seam; ReconcileService routes
pinned services to the agent's command queue (create_container with
image/env/command/ports/volumes/labels/resource limits), tracked in
container_instances with deterministic per-replica ids.
- Stop/start/restart/delete fan out to the pinned node — no more leaked
remote containers on service delete.
- Agent create_container is idempotent (rm -f first) and honors restart
policy, labels, memory/cpus, published+ephemeral ports, volumes, env.
- GET /nodes/options exposes id/name/status to authed users; full agent
management stays admin-only.
- CLI services create/update --node, MCP node_id docs, OpenAPI
node_id/node_name + /nodes/options, service-detail Placement section.
Ceilings: remote nodes run registry-pulled images only — git builds,
Traefik domains, and remote sleep detection stay local until
build-on-node and per-node ingress land.

* feat(scheduling): node cordon/drain + schedulable gate
- node_agents.schedulable column; "auto" placement and explicit pins skip
cordoned nodes; already-pinned services keep running (reconcile is
unaffected — cordon is not eviction).
- POST /agents/:id/cordon|uncordon|drain (admin). Drain cordons, removes
every service container via the agent queue, and clears the services'
pins so they redeploy on the local host. Requires the node online —
an offline node can't acknowledge removals.
- CLI nodes cordon|uncordon|drain (drain confirm-gated), MCP
containr_nodes_cordon|uncordon|drain, OpenAPI paths + schedulable
field, node-detail page cordon badge + drain/cordon controls.
- Fix: re-registering an agent no longer resets auto_prune.

* feat(scheduling): remote registry pulls + post-run health check
- Dispatch payload carries the project owner's registry credentials for
the image host; the agent docker-logins for the pull and logs out
after, so private images deploy to remote nodes.
- Completed command payloads get their registry password scrubbed —
secrets don't linger in agent_commands rows.
- Agent verifies the container is still running ~1.5s after docker run;
crash-loops now fail the deployment with the container's last log
lines instead of reporting "running" optimistically.
