**System details:** MacBookPro16,2 (Intel Iris Plus G7, T2), kernel 7.2.7-arch1-Watanare-T2-1-t2, Omarchy 4.0.4-1

## What's wrong

On T2 Macs, Omarchy installs `vulkan-asahi` (the Apple Silicon GPU driver) next to `vulkan-intel`, even though the Mac has no Apple GPU.

The Vulkan driver detection uses an unanchored pattern:

```bash
lspci | grep -iE "(VGA|Display).*$vendor"
```

The T2 chip shows up as a *Non-VGA* device, and `VGA` matches inside `Non-VGA`:

```
00:02.0 VGA compatible controller: Intel Corporation Iris Plus Graphics G7 (rev 07)
e6:00.1 Non-VGA unclassified device: Apple Inc. T2 Bridge Controller (rev 01)
e6:00.2 Non-VGA unclassified device: Apple Inc. T2 Secure Enclave Processor (rev 01)
```

So `[Apple]=vulkan-asahi` fires. The same pattern appears in three places:

- `install/hardware/vulkan.sh` (fresh installs)
- `migrations/1784401744.sh` (pre-quattro backfill)
- `bin/omarchy-upgrade-to-quattro` (`install_hardware_transition_packages`)

`pacman.log` from the install shows it being requested explicitly:

```
[PACMAN] Running 'pacman -S --noconfirm --needed vulkan-intel vulkan-asahi'
```

The effect is small (14 MiB, plus a Vulkan ICD that can never find a device), but it's wrong on every T2 Mac.

## Steps to reproduce

On any T2 MacBook:

```bash
lspci | grep -iE "(VGA|Display).*Apple"   # matches the T2 lines; expected: no output
pacman -Qi vulkan-asahi | grep -E 'Install Reason|Install Date'
```

Or paste this prompt into a coding agent on the machine:

> On this Omarchy install, check whether `vulkan-asahi` is installed and why. Run `lspci`, then test the pattern that `/usr/share/omarchy/install/hardware/vulkan.sh` uses (`lspci | grep -iE "(VGA|Display).*Apple"`), and find the matching `pacman -S` line in `/var/log/pacman.log`. Tell me whether any line it matched is actually a display controller.

## Expected

Only real display controllers match. `vulkan-asahi` is never installed on x86_64, since Apple Silicon GPUs aren't PCI devices.

## Suggested fix

Anchor the match on the lspci class name, which keeps the current VGA/Display semantics exactly:

```bash
lspci | grep -iE "^\S+ (VGA compatible controller|Display controller): .*$vendor"
```

Then add a migration that drops `vulkan-asahi` on x86_64 when a dry run (`pacman -Rs --print`) shows the removal is clean.

Related: #12076, #11259 and #12681 move `vulkan.sh` to sysfs class `0x03` matching, which would fix fresh installs as a side effect. None of them cover `omarchy-upgrade-to-quattro` or remove the package from machines that already have it. A small PR that does both follows.
