feat: add high-perf features and sensor abstraction

Learned from neurophone's optimized neural processing patterns:

New features (Cargo.toml):
- `high-perf`: ndarray + rayon for 10x faster matrix operations
  - Essential for real-time sensor processing (1kHz+)
- `logging`: Structured logging with tracing
- `fast-serde`: Binary serialization with bincode
- `full`: All features enabled

New profile:
- `release-android`: Optimized for mobile (size + thin LTO)
  - Use: cargo build --profile release-android --target aarch64-linux-android

New module (src/sensor.rs):
- Platform-agnostic sensor input abstraction
- SensorType enum (accelerometer, gyro, magnetometer, etc.)
- SensorReading with normalization to neural-friendly features
- SensorBuffer for temporal windowing

Updated dependencies:
- thiserror 2.0 for better error handling
- reqwest 0.12 with rustls-tls
