* fix(memory-wiki): strip fenced code blocks before wikilink extraction extractWikiLinks runs OBSIDIAN_LINK_PATTERN against full markdown including fenced code blocks and inline code spans, causing false positive 'Broken wikilink target' warnings for bash [[...]] test syntax and Scala generics inside code blocks. Strip fenced code blocks and inline code before running the wikilink regex to eliminate code-block false positives while preserving real wikilinks in prose. Fixes #97945 * fix(memory-wiki): strip fenced code blocks before wikilink extraction --------- Co-authored-by: Vincent Koc <vincentkoc@ieee.org>
