feat(rss): add xslt styling and fix non-ascii tag slugs

- Added an XSLT stylesheet to the RSS feed (/rss.xml) to provide a human-readable, styled view in the browser, mirroring the sitemap's design.

- Resolved an issue where non-ASCII characters in blog tags were incorrectly URL-encoded in the sitemap. The slugifyTag utility now correctly sanitizes tags to create clean, readable URLs.
