Three breakages handled:
- hardware.opengl → hardware.graphics (renamed in 24.11). Touches
upboard.nix, douro.nix, batm3.nix, live.nix.
- vaapiIntel dropped — legacy pre-Broadwell driver, removed in
nixpkgs. UP Board (Cherry Trail) and OptiPlex 9030 (Haswell) both
use intel-media-driver, which stays.
- vaapiVdpau renamed → libva-vdpau-driver.
system.stateVersion stays 24.05 — convention is to never bump after
install. Existing Sintra and fresh flashes keep the 24.05 state
semantics; that's correct.
All 8 nixosConfigurations (4 models × {live,installed}) evaluate
clean with zero deprecation warnings on 24.11.
