Refactor patterns to use preset-based API and fix initialization order

- Fix initialization order: initialize self.presets before calling self.select()
- Separate add() and edit() methods: add() creates new presets, edit() updates existing ones
- Update all test files to use add() instead of edit() for creating presets
- Add comprehensive auto/manual mode test
- Remove tool.py (moved to led-tool project)
