### System details

- Omarchy 4.0.4-1, kernel 7.2.5-3-omarchy
- CPU: Intel Core Ultra 7 265U (Arrow Lake-U)
- Camera: Intel IPU **6** (`00:05.0 Multimedia controller [0480]: Intel Corporation Core Ultra 200H/200V Series Processors IPU [8086:7d19]`), sensor `ov08x40` (ACPI HID `OVTI08F4`)

### What happened

`install/hardware/intel/ipu7-camera.sh` installs `intel-ipu7-camera` whenever ACPI lists `OVTI08F4`:

```sh
if grep -q "OVTI08F4" /sys/bus/acpi/devices/*/hid 2>/dev/null; then
  omarchy-pkg-add intel-ipu7-camera
fi
```

The OV08X40 sensor is not unique to IPU7 (Lunar Lake). On this Arrow Lake-U laptop it sits behind an **IPU6**, which the in-tree `intel_ipu6_isys` driver handles. The IPU7 HAL only ships `/usr/lib/libcamhal/plugins/ipu75xa.so`, so `v4l2-relayd@ipu7` fails to build its pipeline as soon as anything opens the "Hardware ISP Camera" loopback (`/dev/video50`), and the camera never produces a frame:

```
v4l2-relayd: g_param_spec_enum: assertion 'g_enum_get_value (enum_class, default_value) != NULL' failed
v4l2-relayd: gst_element_set_state: assertion 'GST_IS_ELEMENT (element)' failed
CamHAL[ERR] HalAdaptor: load_camera_hal_library, failed to open library: /usr/lib/libcamhal/plugins/ipu6epmtl.so: cannot open shared object file: No such file or directory
CamHAL[ERR] HalAdaptor: get_number_of_cameras, function call is nullptr
```

`omarchy hw webcam` still reports success, because it only checks that a device exists.

### Expected

The IPU7 stack should be installed only on IPU7 hardware, e.g. by also checking which IPU driver binds (`intel_ipu6` vs `intel_ipu7`, or the IPU's PCI id) rather than matching the sensor alone. On IPU6 machines, the in-tree driver plus libcamera (`libcamera`, `libcamera-ipa`, `pipewire-libcamera`) is the path that works without an out-of-tree HAL.

### Steps to reproduce

1. Install Omarchy on an Arrow Lake / Meteor Lake laptop with an OV08X40 camera (IPU6).
2. `intel-ipu7-camera`, `v4l2-relayd` and `v4l2loopback-dkms` are installed, and `v4l2-relayd@ipu7` is enabled.
3. `mpv av://v4l2:/dev/video50` (or any app) hangs with no picture; `journalctl -u v4l2-relayd@ipu7` shows the errors above.

### Workaround that works on this machine

```sh
sudo systemctl disable --now intel-ipu7-camera.service [email protected]
echo 'softdep ov08x40 pre: intel_cvs' | sudo tee /etc/modprobe.d/ov08x40-cvs.conf  # keep the load order the IPU7 package enforced
sudo pacman -Rns intel-ipu7-camera
sudo pacman -S libcamera libcamera-ipa pipewire-libcamera
systemctl --user restart wireplumber pipewire
```

libcamera's simple pipeline then drives the sensor at 30 fps and PipeWire offers it as "Built-in Front Camera" (verified with `cam` and a `pipewiresrc` capture). Note that the IPU7 package's `camera-deps.conf` blacklists `ov08x40` so it loads after `intel_cvs`; without the IPU7 package that ordering needs to come from somewhere else.
