refactor: Address PR review comments

- Fix docs: Change 'craft prepare auto' to 'craft prepare' in quick example
- Merge first release logic with version calculation:
  - Use default bump type (minor) instead of hardcoded version
  - Allow explicit bump types to work for first release (e.g., major -> 1.0.0)
  - More consistent code flow
