"""Compatibility shim — the filesystem tools live in `navi.tools._filesystem`.

The single 18-action `FilesystemTool` was split into `FilesystemReadTool`,
`FilesystemWriteTool` and `FileAiTool`.  This module keeps the old helper
imports working for tests and any external tool code; it declares no tool of
its own.
