Function resolve_read_path 

pub fn resolve_read_path(path: &str, cwd: &Path) -> PathBuf

Resolve a path for reading, trying macOS-specific variants if the initial path doesn’t exist.

macOS may store filenames in:

• NFD (decomposed) Unicode form
• With narrow no-break spaces before AM/PM in screenshots
• With curly quotes (U+2019) instead of straight apostrophes
