Crate gsp 

Group Signaling Protocol — signalling sub-protocol of the Group Protocol Stack.

Receive-side pipeline (GSP §7): decrypt (handled by GBP) → check sender authorisation → validate args schema → apply atomically → ACK / NACK.

This crate provides:

• GspSignal — the CBOR-encoded signal envelope.
• GspClient — stateful client that maintains:
  • request_id deduplication;
  • a mute-list;
  • the current membership set (driven by JOIN / LEAVE);
  • signal_type → gbp_core::SignalType decoding.

See gbp-protocol for the underlying frame format.
