Two bugs fixed:
1. handle_transcode was writing cdn_hls_base = "hls/{version_id}" to the DB
even though HLS files were only in a temp dir (never uploaded to Nextcloud).
The stream endpoint then tried to serve this non-existent path, returning 404
and breaking audio playback for every transcoded version. Removed the
cdn_hls_base write — stream endpoint falls back to nc_file_path (raw file),
which works correctly.
2. Added extract_peaks worker job type: lightweight job that downloads audio
and computes waveform_peaks + waveform_peaks_mini only. No transcode, no HLS,
no full analysis.
3. Added POST /internal/reindex-peaks endpoint (protected by internal secret):
finds all audio_versions with null waveform_peaks and enqueues extract_peaks
jobs. Safe to call multiple times. Use after a fresh DB scan or peak algorithm
changes.
