🎯 Add OAuth2 Backward Compatibility While Keeping Cat Theming

- Return standard 'Bearer' token_type for OAuth2 compliance
- Add TigerStyle extensions: tigerstyle_token_type='ScentBearer'
- Support BOTH Bearer AND ScentBearer headers (dual compatibility!)
- Add scent_strength metadata for cat-themed clients
- Update README with dual authentication examples
- Maintain full OAuth2 spec compliance while keeping tiger awesomeness

🐯 Best of both worlds - standards compliance + cat magic!
