Subject: [PATCH] fix(discord): restore Hangul Filler patch for short fields in
 Rich Presence

Re-added the original workaround that pads title, artist, and album fields with the Hangul Filler character (\u3164) if their length is less than 2. This prevents Discord Rich Presence from displaying empty or missing fields when song info is very short.
