fix: resolve SDK version from gen.yaml when release drafter major is lower

During the 0.x → 1.0.0 migration, the release drafter resolves
0.54.0 because no 1.x release exists yet. The new resolve-version
step uses gen.yaml's version when its major exceeds the drafter's,
and falls back to the drafter for steady-state increments.
