HOW TO USE: These patterns parse M3U8/HLS playlists. The key ones
for IPTV M3U parsing are:
  - EXTINF patterns -> duration + channel name
  - tvg-* attributes -> ID, name, logo, group (parsed separately via key=value)
  - group-title -> category grouping
All others are for HLS streaming (.m3u8 variant playlists)
