Nomarchy/pkgs/nomarchy-install/hardware-db.sh
Bernardo Magri cdfe92a089 feat(hardware): hide dual-sensor webcam IR node (fixes dark image) 
A built-in RGB+IR webcam (common on recent ThinkPads, e.g. the T14s AMD
Gen 4) exposes its IR face-unlock sensor as a second, identically-named
"Integrated Camera"; apps that pick it show a dark, 8-bit-greyscale
image. nomarchy.hardware.camera.hideIrSensor disables that node on the
V4L2 PipeWire path (WirePlumber monitor.v4l2.rules) so only the colour
camera is offered, matched by card name (overridable irMatch).

- libcamera is left untouched: an external camera you plug in is never
  affected, and surgical internal-only libcamera scoping isn't possible
  (its distinguishing props bind after the monitor rule runs).
- Only the PipeWire node is hidden; the kernel /dev/video* stays open,
  so Howdy face-unlock still reads the IR sensor directly.
- The installer's hardware-db.sh auto-detects a paired RGB+IR webcam
  from /sys/class/video4linux/*/name and bakes the toggle into
  system.nix; commented example added to the downstream template.

Validated live on a T14s: collapses the four enumerated "Integrated
Camera" entries to one colour source; the exact shipped regex disables
the IR node (confirmed in the WirePlumber log) and leaves libcamera
intact.

# Nomarchy hardware database — sourced by nomarchy-install.
#
# Flat table mapping detected DMI fields to nixos-hardware module names
# (the strings nomarchy.lib.mkFlake's hardwareProfile accepts). Ported
# from the previous iteration (installer/hardware-db.sh at 3bdfc35).
#
# Format (pipe-separated):
# sys_vendor_regex | product_regex | nixos_hardware_module
#
# - Matching is bash `[[ =~ ]]` regex, case-insensitive.
# - First match wins — put more specific entries (e.g. exact model years)
# above broader fallbacks.
#
# To add a new device: grab `/sys/class/dmi/id/product_name` on the
# target machine and add a line. Module names must exist in
# nixos-hardware.nixosModules (mkFlake fails with suggestions if not).
