WHAT IT DOES

What wiki_pages_rebuild_tree does on Mcp Wikijs Mv

WHY IT NEEDS A POLICY

Why wiki_pages_rebuild_tree needs a policy

This tool triggers an internal operation that rebuilds/repairs the page tree structure. It's not a simple read, nor does it delete data outright, but it modifies internal data structures and could have unintended side effects on the folder/page organization. 'Rebuild' and 'repairs' indicate an operational action that executes a structural transformation rather than a simple write or read.
