On Windows, ggshield secret scan pre-commit crashes with [WinError 206] The filename or extension is too long when committing a merge with many files and long file names. ggshield builds a git command line that exceeds Windows path limits.

A fix was merged and shipped in the release after the report, shortening how the git command is constructed. The reporter tested the fix branch and confirmed it resolves the crash.
