Merge 9bb1bd68cd into 40aedaec71

## Summary
Integrate Peloton bike sensor reading using Grupetto project approach for direct hardware access on Android platform.

## Core Components
- **Java Backend**: PelotonSensorService, PelotonSensorBinder, PelotonSensorHelper classes
- **C++ Integration**: Modified pelotonbike class with JNI calls to Java backend
- **Auto-instantiation**: Enabled automatic pelotonbike creation for this branch
- **Build Configuration**: Updated Android manifest permissions and GitHub Actions

## Key Features
- Direct Peloton sensor access via Android system service binding
- Real-time metrics: power, cadence, resistance, speed
- Moving window filtering for resistance spike mitigation
- Power-to-speed conversion using Peloton V1 formula
- Fallback to OCR method when sensors unavailable

## Technical Implementation
- Based on Grupetto's sensor interface approach
- Follows existing NordicTrack GRPC integration pattern
- Uses Android IBinder for Peloton service communication
- Maintains QZ architecture compatibility

## Build Changes
- Android permissions: onepeloton.permission.ACCESS_SENSOR_SERVICE
- GitHub Actions: APK renamed to fdroid-android-peloton-bike-trial
- Auto-instantiation in bluetooth.cpp for pelotonSensorBranch
