Integrate HTML stripping into doc-builder (#684)

* Integrate HTML stripping into doc-builder

- Add HTML stripping functions to src/doc_builder/utils.py
- Strip HTML when writing final markdown files (in write_markdown_route_file)
- Add standalone script src/scripts/strip_html_from_md.py for manual use
- Add README_strip_html.md with documentation

HTML stripping now happens automatically during the build process when creating
SvelteKit markdown routes (+page.md files), removing docstring HTML tags and
converting them to clean markdown with proper formatting.

* Remove HTML stripping workflow steps

HTML stripping is now integrated into the build process itself
(in write_markdown_route_file), so separate workflow steps are not needed.

* Remove standalone script and README

HTML stripping is now fully integrated into doc_builder/utils.py,
so the standalone script and its documentation are no longer needed.
