Browse Source 
Implement a simplified version of STCP functionality.

* **Client Proxy Configuration and Handling**
  - Add `STCPProxyConfig` to the `pxyConfs` slice in `client/proxy/general_tcp.go`.

* **Client Visitor Configuration and Handling**
  - Add `STCPVisitorConfig` to the `cfg` struct in `client/visitor/stcp.go`.

* **Command Registration and Initialization**
  - Add `STCP` to the `proxyTypes` and `visitorTypes` slices in `cmd/frpc/sub/proxy.go`.

* **Configuration Examples**
  - Add example configurations for `STCP` proxy and visitor in `conf/frpc_full_example.toml`.
  - Add example configurations for `STCP` proxy and visitor in `conf/legacy/frpc_legacy_full.ini`.

* **Configuration Structures**
  - Add `STCPProxyConfig` struct and include it in the `proxyConfigTypeMap` in `pkg/config/v1/proxy.go`.
  - Add `STCPVisitorConfig` struct and include it in the `visitorConfigTypeMap` in `pkg/config/v1/visitor.go`.

* **Configuration Validation**
  - Add validation for `STCPProxyConfig` in `pkg/config/v1/validation/proxy.go`.
  - Add validation for `STCPVisitorConfig` in `pkg/config/v1/validation/visitor.go`.
