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 Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

# 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:
|
|
# ./scripts/setup.sh
