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.

My Nomarchy machine

  1. Overwrite the placeholder hardware config with the real one: nixos-generate-config --show-hardware-config > hardware-configuration.nix
  2. Set flake.nix up once (Nomarchy repo URL, your username, optionally a hardwareProfile from https://github.com/NixOS/nixos-hardware — an unknown name fails the rebuild with suggestions). After that the flake is never touched again: your machine lives in system.nix (hostname, services — the login user is created from username automatically) and home.nix (your packages).
  3. git init && git add -A — flakes only see tracked files, including theme-state.json.
  4. System: sudo nixos-rebuild switch --flake .#default
  5. Desktop: nix run home-manager -- switch --flake .#me (afterwards just home-manager switch --flake .#me — it's installed)
  6. Clone/symlink this directory to ~/.nomarchy (or export NOMARCHY_PATH) so nomarchy-theme-sync knows where the state lives.

Day-to-day:

nomarchy-theme-sync list             # 21 shipped presets
nomarchy-theme-sync apply gruvbox    # writes state + home-manager switch
nomarchy-theme-sync bg next          # cycle wallpapers (instant, no rebuild)

The system layer only needs nixos-rebuild when you change system.nix.
