Enhance DX and performance with introspection, warmup, and improved error messages

[Chemaclass]

This PR introduces several developer experience and performance improvements to the container library.

Features

Developer Experience

• Enhanced Error Messages: All exceptions now include actionable suggestions to help developers quickly resolve issues

  • Missing type hints show example code
  • Unresolvable scalars suggest adding default values
  • Frozen/protected services explain why and how to fix

• Circular Dependency Detection: Automatically detect and report circular dependencies with the full dependency chain (e.g., ClassA -> ClassB -> ClassA)

• Container Introspection: New methods to inspect container state for debugging

  • getRegisteredServices() - List all registered service IDs
  • isFactory(string $id) - Check if a service is marked as factory
  • isFrozen(string $id) - Check if a service has been accessed (frozen)
  • getBindings() - View all configured bindings

Performance

• Constructor Method Caching: Cache ReflectionMethod instances to avoid redundant reflection operations
• Optimized Callable Key Generation: Replace expensive md5(var_export()) with spl_object_id() for better performance
• WarmUp Method: Pre-resolve dependencies during bootstrap for faster runtime

  $container->warmUp([UserService::class, OrderService::class]);
