/**
 * Server-side agent runtime status probe.
 *
 *   GET /api/agent/runtime -> { enabled: boolean, runtimeEnabled: boolean }
 *
 * `enabled` reports usability, not intent: the workbench client gates its
 * entry on this field, so it is true only when the runtime can actually serve
 * a request — the flag AND a `DATABASE_URL` (the runner and every
 * persistence-touching route need the store). `runtimeEnabled` carries the
 * raw intent flag so a client can tell "off by choice" (`runtimeEnabled:
 * false`) from "on but unusable" (`runtimeEnabled: true`, missing
 * DATABASE_URL).
