fix(monorel): init skips auto-bump when other commits precede goreleaser.yaml

Extract findLatestStableTag helper to avoid duplicating tag-scan logic.

In initModuleGroup, count commits since the last stable tag after writing
.goreleaser.yaml. Only auto-bump when ≤1 new commit exists (i.e. the
goreleaser.yaml addition is the sole change). When more commits are present,
print a note and let the user run 'monorel bump' explicitly with the right
semver component.
