Include index and formatted durations in exports

Enhance playlist export output for Text and CSV formats. Text files now include a numeric index, a title fallback ("Video N"), and a human-readable duration ([H:MM:SS] or [MM:SS]) when available before the URL. CSV export adds a "Playlist Index" column and writes a formatted title with index and duration. Duration parsing is protected against non-integer values. M3U and JSON export behavior unchanged.
