MCP server that finds and safely removes "undeletable" files on Windows.

Windows reserves device names like `CON`, `PRN`, `AUX`, `NUL`, `COM1`-`COM9`, and `LPT1`-`LPT9` at the Win32 layer. Files with these names can exist on NTFS (created via WSL, Linux tools, or low-level APIs) but become impossible to rename, move, or delete through Explorer or normal shell commands.

NullOut scans for these hazardous entries and removes them safely using the `\\?\` extended path namespace, with a two-phase confirmation workflow designed for MCP hosts.

## How it works

1. **Scan** an allowlisted directory for reserved-name collisions, trailing dots/spaces, and overlong paths
2. **Plan** the cleanup — NullOut generates a per-entry confirmation token bound to the file's identity (volume serial + file ID)
3. **Delete** with the token — NullOut re-verifies the file hasn't changed (TOCTO…
