Major updates:
- Add Note Limit (1-7) to pattern settings - restricts which notes from scale are used
- Fix pattern length and note limit to use proper armed system
- Both settings now arm (orange) and apply at pattern end without interference

Changes:
- Add virtual environment setup as recommended installation method
- Keep legacy global installation options for experienced users
- Add Python version requirements (3.8+)
- Provide clear guidance on which installation method to choose
- Update running instructions for both virtual env and global installs
- Cross-reference README_VENV.md for detailed virtual environment docs
The guide now recommends the automated virtual environment setup while
preserving the original Windows-specific installer for users who prefer
global installation or need fallback options.

Volume Pattern Improvements:
- Volume patterns now use pattern length as "bar length" for timing
- Swell pattern: completes one full cycle per pattern length
- Breathing pattern: completes two breath cycles per pattern length
- Build pattern: builds over pattern length, fades over 2x pattern length
- Fade pattern: fades from max to min over pattern length

- All patterns now scale dynamically with user-selected pattern length
Delay Timing Enhancements:
