Overview

Drop-in Rust reimplementation of Style/FileNull.

Rust reproduces the whole detection: the file-level /dev/null tally that gates a bare nul (stock's @contain_dev_null_string_in_file), the acceptable? array / hash-pair exemption, the valid_string? empty / invalid-encoding guard, and the REGEXP full match against /dev/null / NUL / NUL: (case-insensitive). It returns one [start, end, message] per offense (message carries the original-case source value); the offense range is also the File::NULL replace range, so the wrapper just applies them. Config-less, so it is always bundle-eligible for config purposes; the shared bundle_eligible? guard only guards the raw-vs-buffer byte identity (CRLF / BOM).

Config-less: contributes nothing to nums / lists. Kept for the 4+1 single-source-of-config convention.
