Closes #474
Problem
Rendered markdown content could contain malicious link protocols (e.g.
javascript:,data:), making the application vulnerable to XSS injection.Current Behavior
Links are rendered directly.
Why This Improvement Is Needed
Filtering protocols prevents script injections from AI generation inputs.
Proposed Solution
Parse and sanitize Markdown link elements using protocol check rules.
Expected Outcome
Secure link parsing without XSS vectors.
