eliott 8c478836d8 feat: ONNX face detection, IR camera support, and PAM authentication
Wire up ONNX RetinaFace detector and MobileFaceNet embeddings in the CLI
and auth pipeline. Add IR camera detection for Windows Hello-style
"Integrated I" cameras and greyscale-only format heuristic. Add histogram
normalization for underexposed IR frames from low-power emitters.

- Add `onnx` feature flag to CLI crate forwarding to daemon
- Wire ONNX detector into `detect` command with fallback to simple detector
- Fix IR camera detection for Chicony "Integrated I" naming pattern
- Add `normalize_if_dark()` for underexposed IR frames in auth pipeline
- Load user config from ~/.config/linux-hello/ as fallback
- Update systemd service for IR emitter integration and camera access
- Add system installation script and ONNX runtime installer
- Update .gitignore for local dev artifacts

# Linux Hello - Complete Setup Script
#
# This script sets up everything needed to use Linux Hello:
# 1. Downloads ONNX face recognition models
# 2. Installs ONNX Runtime (for older glibc systems)
# 3. Builds the project
# 4. Installs the PAM module
# 5. Guides through face enrollment
#
# Usage:
