Purpose: the maintainer, 2026-09-30: "cgi should report daemon health".

Shape: - Daemon.health: whether one runs (its lock), its pid, when it started, the release it runs, the sessions it is the parent of (from the process table), and the end of its log. - The daemon writes the release it started from into its lock (Daemon.claim), resolved through `current` when it starts, since its command line only says `current`. - The Sessions page starts with one line, e.g. "Daemon. Running since TIME (pid N), release R; the parent of K sessions". It flags a daemon on another release than the current one. When the daemon isn't running, it says each page starts it and shows the end of its log. - /state gains a `daemon` object, and its schema follows.

Origin: opus, on the maintainer's request in the terminal. Intent: the daemon's state is seen where sessions are, and read by Stone. Expression: src/ocx/daemon.cr, tools/ocxd.cr, src/ocx/cgi_workspaces.cr, src/ocx/host_state.cr, docs/design/state.schema.json. Demonstrates: spec/ocx/daemon_spec.cr, spec/ocx/console_workspaces_spec.cr, crystal run ci.cr: - not running, health says so and the page shows its log; - running, health gives this pid, release "one" and its child session, and the page gives the line; - a daemon on release "zero" is flagged as not the current release; - CI green, 224 examples, coverage 96.3%.
