feat: Complete Milestone 5 - Platform-Specific Implementations
Implemented platform-agnostic accelerometer abstraction with iOS and desktop implementations:
**IAccelerometerService Interface:**
- Platform-agnostic abstraction for sensor input
- SensorReading model (renamed from AccelerometerData to avoid MAUI conflict)
- X, Y, Z acceleration values in g-force units
- ReadingChanged event for continuous data stream
- Start/Stop methods for sensor control
- IsSupported property for platform capability detection
**IosAccelerometerService (10 tests):**
- Uses MAUI's Microsoft.Maui.Devices.Sensors.Accelerometer
- Works on iOS devices and simulator (provides simulated data)
- Conditional compilation (#if IOS || MACCATALYST)
- Converts MAUI AccelerometerData to our SensorReading
- Graceful failure when sensor unavailable
- Pragma directives for conditional warnings
**DesktopAccelerometerService (11 tests):**
- Timer-based simulated sensor readings (~60Hz)
- Generates realistic noise around 1g gravity baseline
- Device-at-rest simulation: X≈0, Y≈0, Z≈1
- Includes SimulateShake() method for manual testing
- Always reports IsSupported=true (simulation available)
**ShakeDetectionService Integration:**
- Updated constructor to require IAccelerometerService (breaking change)
- StartMonitoring: subscribes to ReadingChanged, calls accelerometer.Start()
- StopMonitoring: unsubscribes and calls accelerometer.Stop()
- OnAccelerometerReadingChanged: pipes readings to ProcessAccelerometerReading
- All existing shake detection logic unchanged
**Platform-Specific DI:**
- MauiProgram.cs uses conditional compilation
- iOS/macOS Catalyst: IosAccelerometerService
- Desktop/other platforms: DesktopAccelerometerService
- All services registered as Singleton
**Test Updates:**
- ShakeDetectionServiceTests: now uses NSubstitute mock accelerometer
- ServiceIntegrationTests: uses DesktopAccelerometerService
- AccelerometerServiceContractTests: base class for implementation tests
- IosAccelerometerServiceTests: 10 tests with platform-aware assertions
- DesktopAccelerometerServiceTests: 11 tests with async timing
**Technical Details:**
- SensorReading record type with required init properties
- Value equality for SensorReading (record type benefit)
- Timer disposal in DesktopAccelerometerService
- Event subscription safety (check for null, unsubscribe on stop)
- 189 tests passing (165 previous + 24 accelerometer)
- 0 warnings, 0 errors across all platforms
Build verified: net8.0, iOS (net8.0-ios), macOS Catalyst (net8.0-maccatalyst)

feat: implement services layer with TDD (Milestone 2)
Implemented all core services following strict TDD (RED-GREEN-REFACTOR):
**Services Implemented:**
- EstimateService: Generate estimates with intensity-based range selection
- StorageService: SQLite persistence with auto-pruning
- ShakeDetectionService: Accelerometer-based shake detection
**Features:**
- Cryptographically secure RNG for estimate selection
- Easter egg logic (>15s shake → Humorous mode)
- Intensity-based range calculation (0-0.3: 20%, 0.3-0.7: 50%, 0.7+: 100%)
- SQLite with auto-pruning based on MaxHistorySize
- Shake detection with 1.5g threshold
- Duration tracking and intensity normalization (0.0-1.0)
- Event-based notifications (ShakeDataChanged)
**Tests:**
- EstimateService: 25 tests (RED-GREEN-REFACTOR)
- StorageService: 14 tests (RED-GREEN-REFACTOR)
- ShakeDetectionService: 22 tests (RED-GREEN-REFACTOR)
- Integration tests: 10 tests
- Total: 119 tests, all passing
**Quality:**
- Build: 0 warnings, 0 errors across all platforms
- Coverage: 51.28% line (low due to MAUI template), 87.5% branch
- All service/model code has high coverage
