fix: support Windows paths in auto-push file detection

The extractFilePathsFromText regex only matched macOS/Linux absolute
paths (/Users/..., ~/...), causing auto-push to silently fail on Windows
where paths look like C:\Users\...

Added [A-Za-z]:[\/] pattern to match Windows drive-letter paths
alongside existing Unix and tilde paths.
