PR Add Windows Pathing Compatibility

[TWDickson]

Windows compatibility failed due to hardcoded unix path separators in file tree generation and gitignore pattern matching. I have not tested on a Unix based system.

• Normalize paths using filepath.ToSlash() in processor for cross-platform gitignore matching
• Add defensive path normalization to filetree package using strings.FieldsFunc
• Add comprehensive tests for mixed path separators and edge cases

Hey Taylor! Thanks for submitting this!

I tested this locally and found one small issue - the filepath.ToSlash() approach doesn't handle literal backslashes on Unix systems. I believe this will work across both Windows and unix-based systems:

// In filetree.go, replace the normalization logic with:
parts := strings.FieldsFunc(path, func(r rune) bool {
    return r == '/' || r == '\\'
})

This handles both separators directly without string replacement and removes the need for the filepath import (you can remove that too). All tests should pass with this change :)

Updated and it looks like it's working!
