Adds Discord direct messages as a notification channel. Users link their
Discord account via OAuth2 (identify scope only, one-time server-side
state rows); a bot delivers their inbox notifications as DMs.
- Extract the email channel's watermark sweep into a generic
account-channel engine; email and Discord are now thin adapters, so
the SKIP LOCKED claim / watermark-after-send durability logic exists
once.
- New internal/discord REST client (token exchange, identity, open DM,
send message) — no Gateway connection, no new dependencies.
- Opt-in master switch (notifications.discord_enabled, default off)
gates delivery, linking, capability, and the admin settings reveal.
- Admin UI: credentials (secret + bot token encrypted at rest), dev
portal setup checklist, bot invite link buttons, and a test button
that bypasses the settings read cache and is disabled while
credential edits are unsaved.
- DM failures from missing shared guild (Discord 50007) surface as link
health in user settings and self-heal via capped backoff.
- New combined mode (per_episode_and_digest) for email and Discord:
instant sends all day plus a daily digest recapping the whole window
since the previous digest.

Adds email as a notification channel built on the shared SMTP core
(mail.Sender). Email mode is a per-account preference (off, daily
digest, or per-episode) stored in notification_email_prefs; delivery is
an account-watermark sweep over notification_deliveries that dedupes
cross-profile duplicates, advancing the watermark only after a
successful send. Admin controls cover the channel kill switch, the
per-episode allowance (off coerces those accounts to the digest),
digest hour, and an external URL for deep links inside emails.
Availability is advertised through /notifications/capability and the
user settings page gains an Email section for opt-in.

Implements the notification system foundation and all v1 delivery channels
that need no external infrastructure (specs 00/01/04/05 in
docs/superpowers/plans/notifications/):
Foundation (spec 01):
- episode_availability seeding + per-library seed markers: "newly available"
means newly released to this server, so back-catalog imports and first
scans never flood (verified on dev: 1.13M episodes seeded silently)
- release_events -> profile_series_interest fanout worker with settling
delay, per-series burst caps, FOR UPDATE SKIP LOCKED multi-node claims,
and a guarded last-notified cursor
- interest index maintained via a userstore provider decorator so every
favorites/watchlist/progress mutation path (REST, jellycompat, imports,
playback) feeds it; progress writes only recompute on state transitions
- durable per-profile inbox + read state, forward-sync cursor API,
websocket channel with short-lived single-use handshake tickets
- web UI: sidebar badge, inbox page, toasts, per-profile preferences
- startup/daily tasks: availability seeding, interest rebuild, retention
Outbound webhooks (spec 04):
- Discord embeds (text-only per the v1 privacy contract) and generic
JSON signed Stripe-style with per-webhook secrets
- HTTPS-only + private-destination guard enforced at registration and at
connect time (DNS-rebinding mitigation); URLs/secrets encrypted at rest
- durable per-target outbox enqueued in the fanout transaction, lease-based
claims, 24h exponential retry, 3x-consecutive-4xx auto-disable with an
in-app notice (loop-guarded)
Web push (spec 05):
- VAPID keypair self-provisioned at startup (single atomic JSON setting,
private half encrypted at rest) — no third-party accounts needed
- payloads E2E-encrypted (RFC 8291); 404/410 treated as unsubscribe
- service worker + subscribe flow in Settings -> Notifications
Shared SMTP core (internal/mail):
- feature-agnostic mail.Sender over live email.* settings, STARTTLS or
implicit TLS, encrypted password, admin Email settings page with
synchronous test send; no consumer yet by design (digest is v1.5)
APNs/FCM (specs 02/03) are deferred to v2; the capability endpoint reports
them unavailable so clients render truthfully.
