feat(scenes): complete rock scene description generator (#607)

Replace placeholder generator with full implementation mirroring pop
generator pattern: 10 rock songs × 10 beats = 100 lyric→scene sets.

Each record includes:
- song, artist, beat, timestamp, duration ("30s")
- lyric_line (actual rock-style lyrical content)
- scene { mood, colors, composition, camera, description }

Generator writes to both:
  training-data/scene-descriptions-rock.jsonl
  ~/.hermes/training-data/scene-descriptions-rock.jsonl

Validates: 100 rows, 10 songs, scene field completeness.
Runs schema validation via validate-scene-data.py if available.
