Jason Woltje aa14b580b3 fix(#337): Sanitize HTML before wiki-link processing in WikiLinkRenderer
- Apply DOMPurify to entire HTML input before parseWikiLinks()
- Prevents stored XSS via knowledge entry content (SEC-WEB-2)
- Allow safe formatting tags (p, strong, em, etc.) but strip scripts, iframes, event handlers
- Update tests to reflect new sanitization behavior
