fix(ci): pin x64 Node for x86_64-apple-darwin matrix entry

The x86_64-apple-darwin job runs on an arm64 Mac runner under Rosetta.
Without explicitly requesting x64 Node, oxc-project/setup-node installs
the runner's native arm64 Node and fspy's x86_64 preload dylib can't be
injected into spawned node processes, breaking the node_fs tests.

Pass architecture: x64 conditionally when matrix.target is the cross
target; other targets get the default (runner-native) Node.
