Massively expanded all 8 caller topic pools from ~1200 to ~2500 entries to
reduce repeat calls. Added persistent topic history (data/used_topics_history.json)
with 30-day aging to prevent cross-episode duplicates. Published episode 35.

New 13-step pipeline:
- De-essing (split-band sibilance compression)
- Breath reduction (detect + attenuate by -12dB)
- HPF integrated into denoise step (80Hz rumble cut)
- Stereo imaging (host center, caller slight right, music Haas widening)
- Silence trimming (head/tail dead air removal)
- Fade in/out (equal-power sine curve, 1.5s/3.0s defaults)
- Auto chapter detection from stem activity
- Episode metadata (ID3 tags: title, artist, album, track, artwork)
Every new feature has a --no-* flag to disable individually.
Revert this commit to restore previous 9-step pipeline.

New stem recording system captures 5 time-aligned WAV files (host, caller,
music, sfx, ads) during live shows. Standalone postprod.py processes stems
into broadcast-ready MP3 with gap removal, voice compression, music ducking,
and EBU R128 loudness normalization.
