Subject: [PATCH] Fix ignore on Windows

`fileMatches` will receive paths with native path separators(i.e. `\` on Windows). Per the [doc](https://github.com/bmatcuk/doublestar/tree/v4?tab=readme-ov-file#match) `doublestar.Match` doesn't work as expected with `\`, and `filepath.ToSlash()` should be used to handle such case.
