v0.1.1 - URL Validation and Typing Improvements

Refactor: URL Validation and Typing Improvements

This release overhauls the handling and validation of URL fields to align with msgspec 0.19.0 capabilities and improve robustness.

Key Changes:

• feat(validation): Switched URL validation from a custom URL class and converter to using typing.Annotated[str, msgspec.Meta(pattern=URL_PATTERN)]. This leverages msgspec's built-in, efficient pattern matching for validation.
• fix(generator): Updated the code generation logic (generate.py) to correctly include necessary imports (typing.Annotated, msgspec.Meta) when generating models with URL fields.
• fix(mapping): Updated the internal Schema.org-to-Python type mapping (mapping.py) to reflect the new Annotated approach for URLs.
• test: Added a new test suite (test_url_validation.py) specifically for verifying the URL regex pattern and the validation behavior within msgspec.Structs.
• test: Refactored existing tests that were skipped or failing due to the previous incompatible URL validation method. All tests now pass.
• docs: Updated README.md to accurately describe the pattern-based URL validation mechanism and remove references to the old converter method.

Notes:

This refactor resolves the incompatibility issues encountered with the previous URL validation approach in msgspec v0.19.0. The new method is more idiomatic, performant, and directly uses msgspec's intended validation features.
