Function get_matching_files

pub fn get_matching_files<P: AsRef<Path>>(
    dirname: P,
    include_patterns: &[String],
    exclude_patterns: &[String],
) -> Result<Vec<PathBuf>, Box<dyn Error>>

Gets matching files from a directory using include and exclude patterns.

This function implements the same logic as Sphinx’s get_matching_files:

• Only files matching some pattern in include_patterns are included
• Exclusions from exclude_patterns take priority over inclusions
• The default include pattern is “**” (all files)
• The default exclude pattern is empty (exclude nothing)
