bump-version

Increment semantic version numbers using controlled preview-then-apply workflow to update plugin metadata safely. Use when (1) after completing a set of changes that need version increment before release, (2) when preparing to sync versions across metadata files using sync-versions, (3) before creating a release tag or publishing to the marketplace, (4) when explicitly requested with a specific bump type, (5) after merging a pull request that requires version increment according to changelog, (6) when planning release schedules and need to calculate what the next version would be.
