fix(analysis): decode Opus in waveform and loudness pipeline (#883)

* fix(analysis): decode Opus in waveform and loudness pipeline

Playback already registered symphonia-adapter-libopus; the analysis crate
used the default Symphonia codec registry without Opus, so .opus tracks
failed at decoder creation. Mirror the audio codec registry, pass format
hints from file suffix and OggS sniffing, and thread hints through the CPU
seed queue.
