Audio File Naming and Caption Improvements

Changes Made

1. Frontend (public/script.ts)

• Added performer field to /api/convert request
• Now sends artist name along with title and other metadata

2. Backend (src/server.ts)

• Updated /api/convert endpoint to accept performer parameter
• Modified filename generation to include artist name:
  • Format: {artist} - {title}.mp3 (when artist available)
  • Fallback: {title}.mp3 (when no artist)
  • Limited artist name to 20 chars, title to 30 chars for safe filenames

3. Bot (src/bot.ts)

• Removed "🎵 ..." text from audio message captions
• Changed caption: \🎵 ${title}`tocaption: undefined`
• Audio files now show clean filename without emoji prefix

Result

Audio files now have proper names like "Artist Name - Song Title.mp3" and no caption text, making them cleaner in Telegram chats.
