feat: Replace RondevuConnection with RondevuPeer state machine

- Created type-safe EventEmitter with generics
- Implemented state pattern for peer connection lifecycle
- Added comprehensive timeout handling for all connection phases
- Removed client-provided offer IDs (server generates hash-based IDs)
- Replaced RondevuConnection with RondevuPeer throughout
- Added states: idle, creating-offer, waiting-for-answer, answering, exchanging-ice, connected, failed, closed
- Configurable timeouts: ICE gathering, waiting for answer, creating answer, ICE connection
- Better error handling with 'failed' event and error details
