Implement PSR-11 ContainerInterface

[giuscris]

This pull request updates the dependency injection container to implement the PSR-11 standard (psr/container) and improves error handling by introducing custom exception classes that conform to PSR-11 interfaces. The changes ensure better interoperability with other libraries and provide more precise exception types for container-related errors.

PSR-11 Compliance:

• The Container class now implements Psr\Container\ContainerInterface, making it PSR-11 compliant and compatible with other libraries expecting a standard container interface.

Improved Exception Handling:

• Introduced custom exceptions: ContainerException and ServiceNotFoundException, both implementing the corresponding PSR-11 interfaces for better error granularity and standardization. [1] [2]
• Updated the container logic to throw these new exceptions instead of generic LogicException for various error cases, such as aliasing to self, missing services, and invalid variadic arguments. [1] [2] [3] [4]
• Modified ServiceResolutionException to implement ContainerExceptionInterface, aligning it with PSR-11 requirements.

Dependency Updates:

• Added psr/container as a required dependency in composer.json to support PSR-11 compliance.
