- MeetingRoomPresenceEvent (kind 10312) now extends BaseReplaceableEvent
instead of BaseAddressableEvent. NIP-53 states this kind is a regular
replaceable event ("presence can only be indicated in one room at a
time"), and LocalCache already routes it through consumeBaseReplaceable.
createAddress/createAddressATag/createAddressTag now take only pubKey.
- Add TagArrayBuilder extensions for streaming (30311), meeting space
(30312) and meeting room (30313) tags, plus build() helpers that assemble
the required tags per NIP-53.
- Add ProofOfAgreement utility to sign and verify the schnorr proof that
NIP-53 places in the 5th element of a participant p-tag
(SHA256 of kind:pubkey:dTag signed by the participant's private key).
Includes LiveActivitiesEvent.hasValidProof() convenience.
