Subject: [PATCH] fix(snapshot): support non-ASCII filenames in undo/revert
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add -c core.quotepath=false to git diff commands to prevent
escaping of non-ASCII characters (e.g., Chinese, Japanese, Korean)
in file paths.

Without this fix, files with non-ASCII names are stored as
octal-escaped strings (e.g., "\345\205\254\345\205\261") in
the patch data, causing undo/revert to fail because git cannot
find these incorrectly-named files.

Tested with Chinese filename: 公共函数.cpp
- Before: undo fails silently for non-ASCII filenames
- After: undo correctly reverts files with any filename
