Subject: [PATCH] fix: improve tool search with camelCase tokenization and
 exact name matching
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Split camelCase/PascalCase into words (sitemapReadTool → sitemap read tool)
- Add +100 score boost for exact tool name matches
- Fixes issue where searching exact tool name returned 0 results
