fix: verify scene-descriptions-rock.jsonl has no placeholders (#632)

The rock scene descriptions file is already clean — no placeholder
lyrics ([Beat N]) or placeholder colors found.

Added tests/test_no_placeholders.py to prevent regression:
  test_no_placeholder_lyrics: no [Beat N] in lyric_line
  test_no_placeholder_colors: no 'placeholder' in colors
  test_descriptions_are_specific: descriptions > 20 chars

3 tests + 300 subtests (all 9 genre files checked)
