* **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
