/**
 * The project bus seam (DES-PROJECT-001 §4) — crew's side of the conversation.
 *
 * Two halves, one bus handle:
 *
 * 1. EMIT `wicked.crew.project.{created,updated,archived}` and
 *    `wicked.crew.membership.{attached,detached}` — always POST-COMMIT (the route handlers call
 *    these only after the engine's reply, so a phantom event for a write that never landed cannot
 *    exist). Idempotency keys are TYPE-INCLUSIVE (DES-EXEC-001 rev0.2 correction #4a — two event
 *    types sharing a key silently drop one on the bus's UNIQUE constraint) and occurrence-unique
 *    (an attach after a detach is a new fact, so the key carries the attach timestamp).
 *
 * 2. BRIDGE `wicked.interactive.*` events that carry a `project_id` onto the daemon's `/ws`
 *    stream as `projectActivity` frames, so an open project view sees creator-skin progress live
 *    without a reload (ADR §5.2 / §8 step 7). The durable feed read is `activity.ts`; this is
 *    only the liveness tap.
 *
 * Posture mirrors the QE/interactive-draft seams: the bus is OPTIONAL. A machine without
 * wicked-bus (or with a broken db) gets a loudly-logged null — project CRUD keeps working, the
 * events simply don't ride, and the daemon boots regardless.
 */
