Mix a music / audio track onto an existing video via ffmpeg. Three modes: replace (drop original audio), overlay (mix both audible), duck (sidechain-compressor lowers music when speech is detected). Volume + fade-in + fade-out controls. No API calls — pure ffmpeg. Use when the user says 'mix this music onto the video', 'add background music to video', 'duck the music under voiceover', 'смешай музыку с видео', 'фоновая музыка для видео'.
