Adds PSKChannel class that wraps PSK v1.1 primitives into a complete conversation manager — matching ts-algochat's PSKManager API surface. New features: - PSKChannel: encrypt/decrypt with automatic counter management - Key rotation with grace period for in-flight messages - Peer public key auto-discovery from first received message - Transaction deduplication via txid tracking - Message callbacks for event-driven usage - State persistence/restoration support - Exchange URI creation from channel Client integration: - AlgoChat.create_psk_channel / get_psk_channel / is_psk_contact - AlgoChat.encrypt_psk / decrypt_psk convenience methods - process_transaction now auto-detects PSK v1.1 messages 29 new tests covering round-trips, replay protection, key rotation, session boundaries, bidirectional decrypt, and state persistence.
