Finds pages in your Obsidian vault that cover the same concept under different names (like "RSC" and "React Server Components") and merges them into a single canonical page. It scores pairs by title similarity, aliases, and tags, then reads the content to decide whether they're truly duplicates or just related. Runs in audit mode by default so you can review before it does anything destructive, or you can auto-merge high-confidence matches. Useful when your wiki has accumulated accidental duplicates or you've been inconsistent with abbreviations. Heavier than wiki-lint since it actually rewrites pages and creates redirect stubs, so the confirmation step matters.
