/**
 * DES-TEAMING-002 §4.5 (seam T8) — the `wicked.team.*` → `/ws` relay.
 *
 * The engine publishes every team fact on the bus (§4.0, one owner per type, §7). This relay puts
 * each new team row on the SAME `/ws` socket the studio already holds, as
 * `{ type: 'teamEvent', event: <the bus row> }`, tagged `project_id` when the run's membership
 * files it, as every CoreEvent frame is. No CoreEvent variant carries a team event, and crew never
 * puts a team row on the bus (tests/team-no-publish.test.ts).
 *
 * READ-ONLY. The bus file is the engine's (T0), and crew reads it through the engine that holds it
 * (`Core.busRead`, wicked-core#631, core/bus.ts) — crew opens no SQLite of its own. The relay is a
 * tap with its cursor in memory, starting at the newest row (`latest`). Nothing is lost that
 * matters: the bus is the durable record and `GET /runs/:id/team` reads it back, so a restart needs
 * no stored cursor.
 *
 * Posture: loud, non-fatal. A bus no engine holds → one log line and `null`; `/ws` then
 * carries no team frames. A read that fails (the engine mid-checkpoint) is logged and retried on
 * the next poll.
