// ===== task.signal.ts =====
// Convention: <module>.signal.ts — the API surface for a database module.
// Extends endpoint(srv.<module>, ...) from akanjs/signal — binds to the service to define query/mutation/pubsub.
// endpoint() receives: { query, mutation, pubsub, message } — each typed with the model's return type.
// .param() = URL path parameter, .body() = request body, .search() = query string.
//
// Auto-generated by akan sync (do not write manually):
//   viewTask(id) — fetch single task for detail view
//   editTask(id) — fetch task for edit view
//   mergeTask(id, data) — create/update task
// Manual endpoints below: only define endpoints that need custom business logic.
// Registered by akan sync into sig.ts barrel.
