/**
 * `weft.system.metrics` operation + REST binding.
 *
 * Returns JSON-shaped metrics. This is distinct from the Prometheus text
 * exposition at `GET /v1/metrics` (which remains a direct handler and is
 * REST-only). This operation exposes the same underlying data as a
 * structured JSON object for consumers that need machine-readable metrics
 * rather than Prometheus text format.
 *
 * Access is scoped to `system:read` — the same privilege class as any
 * internal-observability endpoint.
 *
 * The metrics snapshot comes from server-owned state captured when the
 * operation is registered. Callers cannot supply a snapshot through REST
 * or JSON-RPC input.
