test: regenerate gcd rules-base.json for yosys 0.64

The bazel-orfs/orfs bump moves the flow to yosys 0.64, whose synth output
no longer emits synth__design__instance__area__stdcell (and adds
synth__canonical_netlist__hash / synth__netlist__hash). The stale gcd
rules-base.json required the dropped metric, so gcd_test/gcd_b_test failed
checkMetadata with "Value not found for synth__design__instance__area__stdcell".

Regenerated via `bazelisk run //test/orfs/gcd:{gcd,gcd_b}_update_rules`
(identical output for both variants). gcd_test and gcd_b_test now pass.
