Subject: [PATCH] Fix repeated follower OS notifications
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Kind 3 events are replaceable — same person produces a new event
ID every time they update their contact list. Dedup followers by
pubkey instead of event ID to prevent re-notifying.
