Michael Winter 62e6a75f4f Add harmonic compactness factor 
- Compute sum of harmonic distances between all pitch pairs
- Lower sum = more compact chord = higher probability
- Uses pitch_difference() to get diff, then log2(n*d) for distance
- Add CLI arg: --weight-harmonic-compactness

Michael Winter 863423ca7a Add uniform symdiff selection and store symdiff in graph edges 
- Add symdiff to edge tuple in _find_valid_edges() and store in graph
- Add --uniform-symdiff CLI option to make symdiff selection uniform
- Implement uniform selection in pathfinder by grouping edges by symdiff
- With uniform: path uses symdiff 2 and 4 roughly equally
- Without uniform: path uses mostly symdiff 4 (most common)

Michael Winter 559c868313 Fix Hamiltonian analysis and add DCA stay count metrics 
- Save graph_path to output for accurate Hamiltonian tracking

Michael Winter 34a6ebfabd Add per-factor analysis metrics

- Target range: start/end cents, achieved percentage
- CLI: --stats now shows all metrics automatically

Michael Winter 737f1e4886 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
