Replaces ObservableEventStore.events: SharedFlow<Event> with
SharedFlow<StoreEvent>, where StoreEvent is:
Insert(event)
Delete(rule: DeleteRule)
DeleteRule.Filtered(filters) ← from delete(filter) / delete(filters)
DeleteRule.Expired(asOf) ← from deleteExpiredEvents()
ObservableEventStore now emits Insert for accepted events, and Delete
for every out-of-band removal that went through it. The Expired rule
carries the cutoff timestamp (TimeUtils.now() at call time) so the
projection's in-memory drop matches the store's on-disk drop without
clock skew between collectors.
EventStoreProjection no longer runs its own NIP-40 ticker. Expired
events linger in [items] until the application calls
deleteExpiredEvents() on the observable — at which point the
projection drops everything whose expiration is past `asOf`. The
ticker, expirationTickMs constructor arg, and sweepExpired helper are
all removed.
For DeleteRule.Filtered the projection iterates current slots and
drops any whose event matches any of the rule's filters via
Filter.match — same predicate the store uses.
Tests:
- nip40ExpirationDroppedByTicker → nip40ExpirationDroppedOnStoreSweep:
drives a deleteExpiredEvents() call instead of waiting on a ticker.
- New deleteByFilterRemovesMatchingSlots: confirms delete(filter) on
the observable removes exactly the matching slots from the projection
without touching others.
- 15/15 projection tests + all other store tests pass.
