[sn]

This pull request focuses on significantly improving the documentation and clarity of the HTMLElement class and its methods in the NitroUI library. The changes add detailed docstrings, clarify method behaviors, and provide usage examples, making the API much more approachable for users and contributors. There are no functional or behavioral changes—only enhancements to documentation and developer experience.

Enhanced documentation and clarity:

• Added a comprehensive class docstring to HTMLElement, explaining its purpose, usage patterns, and attribute conventions.
• Updated docstrings for all major methods in HTMLElement (e.g., __init__, append, prepend, add_attribute, add_style, filter, etc.) to include descriptions of arguments, return values, raised exceptions, and usage examples. [1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11] [12] [13]
• Improved the docstring for the template method in Component, clarifying how props and slots are handled.

Other minor updates:

• Bumped the package version from 1.0.9 to 1.0.10 in pyproject.toml to reflect these documentation improvements.
