Add per-factor analysis metrics
...
- Melodic: violations, max violation, avg movement
- Contrary motion: steps with contrary, percentage
- DCA: avg voices changing, all voices change count/percent
- Hamiltonian: unique nodes, coverage percentage
- Target range: start/end cents, achieved percentage
- CLI: --stats now shows all metrics automatically

Refactor edge weights with DCA and CLI improvements
...
- Implement DCA (Dissonant Counterpoint Algorithm) to favor voice changes
- Track actual pitch changes in voice_stay_count (not graph indices)
- Add CLI weight arguments: --weight-melodic, --weight-contrary-motion,
--weight-hamiltonian, --weight-dca, --weight-target-range
- DCA probability = (sum of stay_counts for changing voices) / (sum of all)
- Test with --weight-dca 100 shows frequent voice changes

Refactor into src/ module with caching and CLI improvements
...
- Split monolithic compact_sets.py into modular src/ directory
- Add graph caching (pickle + JSON) with --cache-dir option
- Add --output-dir, --rebuild-cache, --no-cache CLI options
- Default seed is now None (random) instead of 42
- Add .gitignore entries for cache/ and output/
