Subject: [PATCH] fix: update version numbers to March 2026 reality

- Kernel: 6.18.18 LTS (recommended), 6.19.8 stable (PCIe issues),
  7.0-rc4 mainline added. Updated kernel compatibility table.
- Fedora: 42 marked as EOL everywhere, 43 is current, 44 Beta mentioned
- Mesa: 25.x in Fedora 43, 26.0 on Debian sid. Removed Fedora 42
  mesa-git COPR instructions.
- Updated kernel install examples to use 6.18.18 instead of 6.14/6.16
- Added 6.19.x PCIe warning across all relevant pages
