_detect_gpu matched every _VENDOR_KW key against the whole lspci line. Every display line contains "VGA compATIble controller", so the "ati" key fired unconditionally and "intel" was never reached: Intel iGPUs were reported as AMD, switching on the GPU-accelerated terminal and the AMD-only Electron flags. Match against hw.gpu_model — the description after the last colon, which the line above already extracts — instead of the whole line. The strict=True xfail guarding this is removed and becomes a normal passing regression test, and the two parametrised cases that characterised the bug (Intel -> AMD, unknown vendor -> AMD) are corrected to Intel and Unknown. Added this machine's real second display device, "[AMD/ATI] Raphael", which must still resolve to AMD. Verified by real run: --dry-run still reports the RTX 3090 as NVIDIA with 24576 MB VRAM and still proposes 18 changes, matching the pre-fix baseline. Full gate: 1984 passed, 100% coverage.
