Build, test, and debug regular expressions
Parses filenames (typically for Plex libraries) to separate the studio name from the clip/movie title. It optionally matches a studio wrapped in braces, parentheses, or square brackets at the start of a line, then splits on a delimiter of 2-3 hyphens/spaces or a closing bracket plus whitespace, capturing results in named groups 'studio' and 'clip_name'. The global and multiline flags enable batch processing of multiple filename lines at once.
