getTranscodeDecision was copying the source file's bit depth into the transcodeStream details, so a 24-bit FLAC negotiated to Opus reported audioBitdepth=24. Lossy codecs (Opus, MP3, AAC) have no PCM bit depth, and ffmpeg only honors a bit depth constraint (-sample_fmt) for lossless outputs, so the value was both meaningless and misleading to clients that use it as a quality indicator. Only set the transcoded stream's bit depth when the target format is lossless; a zero value omits audioBitdepth from the response. This also makes audioBitdepth codec limitations a no-op for lossy targets instead of rejecting the profile. Lossless targets (e.g. FLAC->FLAC downconvert) keep reporting and clamping bit depth as before.
