- **Removed legacy build files**:
- Deleted obsolete `.travis.yml`, `flake.lock`, and `flake.nix` files that were no longer needed for the current build and dependency management setup.
- **Updated versioning**:
- Incremented the package version from `0.4.0` to `0.5.0` in `version.py` and made adjustments in `pyproject.toml` to reflect the new versioning mechanism.
- **Refined package structure**:
- Moved source files from `src/python_markdown_oembed_extension` to `mdx_oembed` and renamed references accordingly for better clarity and organization of the codebase.
- **Enhanced OEmbed functionality**:
- Added dedicated endpoint handling in the new `endpoints.py`.
- Refactored the `oembed.py` file to implement a minimal oEmbed consumer, replacing the earlier dependency on `python-oembed`.
- **Improved test coverage**:
- Transitioned tests from `unittest` to `pytest` framework for better maintainability.
- Expanded unit tests, including better error handling and validation for various media types.
- **Updated dependency requirements**:
- Raised minimum Python version from `3.9` to `3.12` in `pyproject.toml`.
- Removed non-essential dependencies and restructured the dependency declarations to streamline package management.
These changes focus on modernizing the codebase, improving adherence to current Python standards, and enhancing overall functionality and maintainability.
