Updates for shared connections and UDP
This alpha updates how shared connections and UDP traffic are handled. The single-instance TCP/Vision + QUIC UDP setup remains available; these changes are not a promise of higher speed on every network.
- Supported hardware can provide cryptographic acceleration, while reused TLS cipher contexts avoid repeated setup.
- When TCP connections are shared with mux, ready streams are scheduled with larger startup windows kept within memory budgets.
- QUIC receives traffic in batches and advances UDP independently; BBR remains the default congestion control.
- Optional numeric diagnostics help inspect transport behavior without reporting destination addresses or credentials.
Upgrade both endpoints for adaptive mux. Review the performance configuration and release verification before deploying.
