SDP payloads (offer, answer, renegotiate) are specific to individual
PeerConnections and cannot be shared across peers. This commit:
- Adds group-context overloads to createCallOffer, createCallAnswer,
and createRenegotiate that include all member p-tags but wrap to
a single target peer
- Removes createGroupRenegotiate (renegotiation is always per-peer)
- Updates sendRenegotiation/sendRenegotiationAnswer to take explicit
peerPubKey and use per-peer wrapping with group p-tags
- Updates invitePeer to include all existing group members + invitee
in p-tags so the new peer sees the full group composition
- Documents SDP per-peer vs sign-once distinction in NIP-AC spec
