Seis funciones de servidor HTTP con tests usando httptest: - HTTPJSONResponse: escribe JSON con Content-Type y status code - HTTPErrorResponse: escribe HTTPError como JSON estructurado - HTTPParseBody: decode JSON con limite de bytes y campos estrictos - HTTPLoggerMiddleware: loguea method/path/status/duration a io.Writer - HTTPRouter: crea ServeMux con rutas Go 1.22+ (METHOD /path) - HTTPServe: ListenAndServe con graceful shutdown por contexto 23 tests pasando, solo stdlib net/http.

## Ejemplo
|
|
|
|
```go
|
|
mux := HTTPRouter([]Route{
|
|
{Method: "GET", Path: "/api/health", Handler: http.HandlerFunc(healthHandler)},
|
|
{Method: "POST", Path: "/api/users", Handler: http.HandlerFunc(createUserHandler)},
|
|
{Method: "GET", Path: "/api/users/{id}", Handler: http.HandlerFunc(getUserHandler)},
|
|
})
|
|
http.ListenAndServe(":8080", mux)
|
|
```
|
|
|
|
## Notas
|
|
|
|
Usa la sintaxis "METHOD /path" de Go 1.22+ para registrar rutas con metodo especifico. Soporta parametros de path como {id} accesibles via r.PathValue("id"). Sin rutas registradas retorna un mux vacio que responde 404 a todo.
