fix: show correct stable versions for patch/minor/major prompt choices on prereleases

Add getNextStableVersion which always produces a stable bump regardless of
whether the current version is a prerelease. Use it in the version prompt so
patch/minor/major choices correctly display and return stable targets (e.g.
1.0.0) while the suggested/next-prerelease options show the prerelease bump.
