New Features: • Add --locked option to run and invoke commands to select locked plugin definitions Enhancements: • Introduce PluginLockBehavior enum to control behavior when lockfiles already exist • Automatically persist plugin definition lockfiles when fetching parents or adding plugins based on preferred source • Simplify the lock command by deferring to project.plugins listing and unified behavior in lock service Tests: • Add tests for SKIP behavior in PluginLockService meltano/meltano
