Changed AddRoute and ListenAndServe methods to return errors instead of logging them internally and continuing. This allows callers to properly handle and propagate errors, improving error visibility and enabling better error management across the codebase. Updated all callers in fileserver, reverse_proxy, stream routes to handle these errors appropriately.
* **New Features**
* Multiplexed TLS port: HTTP API and a custom stream protocol can share one port via ALPN.
* Agent-side TCP and DTLS/UDP stream tunneling with health-check support and runtime capability detection.
* Agents now advertise per-agent stream support (TCP/UDP).
* **Documentation**
* Added comprehensive stream protocol documentation.
* **Tests**
* Extended integration and concurrency tests covering multiplexing, TCP/UDP streams, and health checks.
* **Chores**
* Compose/template updated to expose both TCP and UDP ports.
- Introduced a new `Bind` field in the route configuration to specify the address to listen on for TCP and UDP routes.
- Defaulted the bind address to "0.0.0.0" if not provided.
- Enhanced validation to ensure the bind address is a valid IP.
- Updated stream initialization to use the correct network type (tcp4/tcp6 or udp4/udp6) based on the bind address.
- Refactored stream creation functions to accept the network type as a parameter.
- Remove BytesPoolWithMemory; split into UnsizedBytesPool and 11-tier SizedBytesPool
- Track buffer capacities with xsync Map to prevent capacity leaks
- Improve buffer reuse: split large buffers and put remainders back in pool
- Optimize small buffers to use unsized pool
- Expand test coverage and benchmarks for various allocation sizes
