refactor: rename package from rivet-di to dioxide

Complete package renaming from rivet-di to dioxide across the entire
codebase to better reflect the project's identity and purpose.

Changes:
- Renamed Python package: python/rivet_di -> python/dioxide
- Updated internal attribute: __rivet_scope__ -> __dioxide_scope__
- Renamed Rust module: _rivet_core -> _dioxide_core
- Updated all documentation and configuration files
- Updated GitHub repository references
- Updated all BDD feature files and test imports
- Added CLAUDE.md for development guidance
- Updated git remote URL to github.com/mikelane/dioxide
- Fixed pre-commit hook to use uv run pytest

The renaming maintains backward compatibility in the API surface while
cleaning up all internal references to the old name.
