c5a231b pinned the hash by hand because nixpkgs bumped 1.98.8->1.98.9 without
updating vendorHash (NixOS/nixpkgs#545860). The previous commit's lock moves
nixos-26.05 past the point where that fix was promoted from release-26.05, so
the override is now dead weight — and a stale vendorHash override is worse
than none, since it silently wins over a correct upstream value on the next
version bump.
