feat: Add identify-push raw format support and yamux logging improvements

Browse Source 
- Add comprehensive integration tests for identify-push protocol
- Support both raw protobuf and varint message formats
- Improve yamux logging integration with LIBP2P_DEBUG
- Fix RawConnError handling to reduce log noise
- Add Ctrl+C handling to identify examples
- Enhance identify-push listener/dialer demo

Fixes: #784
