chore: synchronize package versions to 3.0.0-dev.X across all packages

- Unified MAJOR.MINOR versioning across all cherrypick ecosystem packages
- Updated cherrypick_annotations from 1.1.2-dev.2 to 3.0.0-dev.0
- Updated cherrypick_generator from 2.0.0-dev.2 to 3.0.0-dev.0
- Updated cherrypick_flutter from 1.1.3-dev.12 to 3.0.0-dev.1
- Updated documentation URLs from .dev to .netlify.app domain
- Maintained semantic versioning consistency for mono-repository management

This change ensures:
- Clear compatibility signaling between interdependent packages
- Simplified dependency management for consumers
- Consistent release versioning across the ecosystem
