* **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.
- Move health check implementations from monitor/ to new check/ package
- Add h2c, tcp4/6, udp4/6 scheme support to agent health check API
- Add timeout URL parameter to agent health check endpoint
- Remove unused agent dependencies (dnsproviders, lego, various cloud SDKs)
- Use net.JoinHostPort instead of fmt.Sprintf for port joining
Moved non-agent-specific logic from agent/pkg/agent/ to internal/agentpool/:
- pool.go: Agent pool management (Get, Add, Remove, List, Iter, etc.)
- http_requests.go: HTTP utilities (health checks, forwarding, websockets, reverse proxy)
- agent.go: Agent struct with HTTP client management
This separates general-purpose pool management from agent-specific configuration,
improving code organization and making the agent package focused on agent config only.
