fix(memory-wiki): strip fenced code blocks before wikilink extraction (fixes #97945)

zw-xysk · zw-xysk · commit 0f1fcb75829c · 2026-06-30T08:34:22.000+08:00
Fenced code blocks and inline code spans containing [[...]] patterns (e.g. Scala generics Future[Option[User]], bash [[ "" == "y" ]]) were falsely reported as broken wikilink targets. Strip them from the searchable text before running the wikilink regex. This reopens and implements the validated fix from #70986.
