Notify the requesting profile once its media request is actually present
in the catalog (roadmap 06, item 2). Completion transitions stay
notification-agnostic; a presence-gated pass at the end of each
reconcile run fires the notice, so it means "watchable in Silo", not
"download finished".
- New System.DispatchOperational: delivery insert + webhook/web-push
outbox enqueue in one transaction, post-commit multi-dispatch. The
webhook auto-disable notice now rides the same path (replacing its
hand-rolled hub publish and the now-removed InsertOperational), which
also delivers auto-disable notices over web push.
- At-most-once delivery: partial unique index on
(profile_id, reason_flags->>'request_id') plus a fulfilled_notified_at
marker on media_requests, backfilled for pre-existing completed
requests so deploys never flood.
- Per-webhook notify_requests toggle (default on) through repo, service,
API, and settings UI; gated independently of the episode reason flags.
- request.fulfilled rendering in web inbox, realtime toast, web push
payload, and Discord/generic webhook payloads, deep-linking to the
matched catalog item.
