LiveEventStore.query had a race window between emitting EOSE and
registering as a SharedFlow collector — any event emitted in that
window was lost because newEventStream has replay=0. The race was
usually masked by SQLite write latency for persisted kinds, but it
fired reliably for ephemeral kinds (20000-29999) where store.insert
is a no-op.
Per NIP-01 ephemeral events are not persisted but MUST still reach
matching active subscriptions. Fixed by registering the live
collector before signalling EOSE via Flow.onSubscription.
Adds two tests: one proves an ephemeral event reaches an active
subscriber, the other proves it isn't persisted (a follow-up REQ
returns zero events).
