Enable running wraith alongside iroh-blobs, iroh-gossip, and iroh-docs
on the same QUIC endpoint (one connection per peer, multiplexed by ALPN).
- IrohTransport::from_endpoint(node_id, endpoint) for client-side shared endpoint
- IrohAcceptor::from_endpoint(endpoint) for server-side shared endpoint
- Export ALPN constant as IROH_ALPN for Router registration
- Add owned() method to track whether the endpoint was created internally
- Existing new()/bind() constructors unchanged (backwards compatible)
- Add tests for from_endpoint constructors and shared endpoint connectivity
