Release 2.0.0
feat!: redesign Upref around explicit configuration storage
- add a typed ConfigStore API with atomic YAML persistence
- separate interactive prompting from configuration storage
- preserve the legacy v1 API and provide migration support
- modernize packaging, tests, CI, documentation, and Windows shortcuts
BREAKING CHANGE: Upref now requires Python 3.10+ and introduces a new explicit load, collect, and save workflow.
