Add Go HTTP REST API server as alternative to hello_go logging demo

[Copilot]

Requested: Go project with similar structure to sudhirpola/hello_go but different implementation approach.

Created HTTP web server using stdlib net/http instead of third-party logging framework demonstration.

Implementation

• 3 REST endpoints returning JSON:

  • GET / - welcome message
  • GET /api/hello?name={name} - parameterized greeting
  • GET /health - uptime and status

• Build infrastructure matching hello_go pattern:

  • Makefile with build/run/test/clean targets
  • Alpine-based Dockerfile
  • Go module at hello-web-server/

• Error handling: JSON encoding failures log and return HTTP 500

Key Differences from hello_go

hello_go	This Implementation
Demonstrates structured logging (dazl)	HTTP service with REST API
Third-party logging framework	Standard library only
Console output with log levels	JSON HTTP responses
YAML logging configuration	Zero configuration

// Example handler with error handling
func helloHandler(w http.ResponseWriter, r *http.Request) {
    name := r.URL.Query().Get("name")
    if name == "" {
        name = "World"
    }
    
    response := Response{
        Message:   fmt.Sprintf("Hello, %s!", name),
        Status:    "success",
        Timestamp: time.Now(),
    }
    
    w.Header().Set("Content-Type", "application/json")
    if err := json.NewEncoder(w).Encode(response); err != nil {
        log.Printf("Error encoding JSON response: %v", err)
        http.Error(w, "Internal Server Error", http.StatusInternalServerError)
    }
}

Original prompt

i wanted sample similar to https://github.com/sudhirpola/hello_go , but in diff way
