Changed stream_handler to always serve ICY-wrapped FLAC instead of
checking for the Icy-MetaData header. This ensures all clients
(including VLC) receive metadata updates.
Changes:
- Removed conditional ICY/pure FLAC logic
- Always use subscribe_icy() for all connections
- Added standard ICY headers (icy-genre, icy-pub)
- Updated documentation to reflect default ICY mode
This allows clients to see "Now Playing" information without needing
to send specific HTTP headers.
