Michael Winter b349ee89bc Extract DIMS to separate dims.py module 
- Create src/dims.py with DIMS_4, DIMS_5, DIMS_7, DIMS_8 constants
- Update pitch.py to import from dims
- Update harmonic_space.py to import from dims
- Update io.py to import from dims
- Fix circular import issue

Michael Winter 66669de00f Add Path and Candidate classes for path state tracking 
- Add src/path.py with Path and PathStep classes
- Path stores initial_chord, steps, weights_config
- PathStep stores graph_node, output_chord, transposition, movements, scores, candidates
- Refactor find_stochastic_path to use candidates approach
- Separate _build_candidates (raw scores) from _compute_weights
- Simplify return type to Path only (graph_chords available via property)
- Update io.py to use new Path API

Michael Winter 218d7a55ff Refactor DCA factor: rename to DCA Voice Movement and DCA Hamiltonian 
- Rename _factor_dca to _factor_dca_voice_movement (tracks voice pitch changes)
- Rename _factor_hamiltonian to _factor_dca_hamiltonian (tracks node visit counts)
- Update CLI: --weight-dca -> --weight-dca-voice-movement
- Update CLI: --weight-hamiltonian -> --weight-dca-hamiltonian
- Remove hamiltonian coverage from analysis (no longer tracking)

Michael Winter 559c868313 Fix Hamiltonian analysis and add DCA stay count metrics 
- Save graph_path to output for accurate Hamiltonian tracking
- DCA analysis now shows avg/max voice stay counts
- Fix: use actual graph node hashes instead of rehashing transposed chords

Michael Winter 34a6ebfabd 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

Michael Winter 16ecb192d1 Add analysis tool for chord sequences 
- Add src/analyze.py: standalone analysis script
- Add --stats CLI flag to show stats after generation
- Analyze: melodic violations, target range %, voice changes

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

Michael Winter 61149597c9 Add target range weight for rising register 
- Add --target-range CLI option (in octaves)
- Implement target_range weight in PathFinder
- Add test for target range weight
- Add --max-path to README

Michael Winter 0698d01d85 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/
