Subject: [PATCH] build: standardize dependabot config and enable auto-merge
 for minor/patch updates

Groups minor/patch updates for auto-merge once CI passes, keeps majors as
individual PRs for manual review, adds a cooldown window, standardizes the
commit-message prefix to build(deps), and restores default dependency labeling.
