275ad4be4a feat(relay): add NIP-ER push scheduler, ingest relaxation, and NIP-11 advertisement
The relay now proactively delivers due reminders via Redis pub/sub.
Cross-pod dedup uses an atomic delivered_at claim (mirrors the reaper's
archived_at guard). Ingest relaxed to allow kind:30300 without
not_before (bookmarks/terminal states). max_not_before_delta enforced
to prevent unbounded-future scheduling abuse.

Schema: nullable not_before + delivered_at columns on events, partial
index for scheduler queries. NIP-11: supported_extensions ["nip-er"],
due_delivery_mode "push", max_not_before_delta advertised.

Spec (NIP-ER.md) amended: not_before optional on kind:30300, required
only for pending reminders that may become due.

84b0dadee3 fix(relay): relax not_before to optional, add d-tag validation
The spec requires not_before on pending reminders only — terminal states
(done/cancelled) and bookmarks omit it. The validator incorrectly
required exactly one not_before on all kind:30300 events, blocking the
entire completion/cancellation lifecycle.

Also adds d-tag structure validation per spec: reject zero, empty, or
duplicate d tags.

0b3bed62bf feat(relay): implement NIP-ER event reminder support (kind:30300)
Adds relay-side support for NIP-ER encrypted event reminders:

Write path (ingest):
- Register KIND_EVENT_REMINDER (30300) as parameterized replaceable,
  global-only, and UsersWrite-scoped
- Validate not_before tag: exactly one, decimal digits only, no leading
  zeros, range 0..=MAX_SAFE_INTEGER
- Reject expiration <= not_before when both are present and parseable

Read path (REQ/COUNT/bridge):
- AUTHOR_ONLY_KINDS array gates visibility — only the authenticated
  event author may read kind:30300 events
- Exclusive author-only filters (kinds:[30300]) require authors=[self]
  or get CLOSED/403
- Mixed-kind filters pass the gate but per-event filtering silently
  omits other authors' reminders
- COUNT fast path disabled when author-only kinds are in play to
  prevent leaking aggregate counts

Integration tests (e2e_event_reminder.rs):
- Write validation: valid, missing, duplicate, malformed not_before;
  expiration ordering; edge cases (0, MAX_SAFE_INTEGER)
- Read filtering: author self-query, cross-user rejection (HTTP 403
  and WS CLOSED), mixed-kind omission, replacement semantics
