Merge branch 'dev' into claude/debug-upload-blocked-RFGA7

resolveWorkspaceUrls() only handled image syntax ![alt](workspace://id)
but not regular link syntax [text](workspace://id). When the AI returned
file download links using workspace:// protocol, Streamdown's
rehype-harden sanitizer blocked them because "workspace://" is not in
the allowed URL-scheme whitelist, causing "[blocked]" to appear next to
the file name in the chat UI.

Add a second replace pass that catches regular markdown links with
workspace:// and rewrites them to the /api/proxy download path, matching
the existing image-link handling.
