fix: align implementation with spec and expand estimate pools 5x
Critical fixes per spec.md requirements: - Restructure EstimateService with two-pool algorithm (gentle vs hard shake) - Expand all estimate pools to 5x spec size for more variety: * Work gentle: 7 → 35 estimates * Work hard: 12 → 60 estimates * Generic gentle: 8 → 40 estimates * Generic hard: 15 → 75 estimates * Humorous: 9 → 45 estimates - Add NSMotionUsageDescription to iOS Info.plist (required for accelerometer) - Add code coverage enforcement to test workflow (95% minimum per spec) - Update all tests to match new two-pool selection algorithm - Use 0.5 intensity threshold to choose between gentle/hard pools All 193 tests passing. Addresses critical spec deviations identified in code review.
