feat: add explicit cinematic coverage to music-moods prompt enhancement (closes #601)

- Replace 9 non-cinematic entries with 9 cinematic variants
- Now explicitly covers all 4 required domains: ambient, jazz, electronic, cinematic
- Maintains exactly 500 entries total
- New cinematic terse: cinematic epic solo/duet/trio/ensemble/remix/reprise/ost/suite/theme

Issue #601 acceptance: all 4 domains now explicitly represented in terse prompts.
