Removes temporary verification screenshots, docker files and verify.html
introduced for PR #58 validation.
- Before/after images and real-app screenshots remain accessible in history
at e51cabb for PR review but are not needed in main
- Keeps only the actual fix: internal/query/championship.go + test
- Maintains docs/ structure without binary clutter (PRODUCT_ROADMAP, assets, etc.)
Fixes#57 remains: Sprint points now included (ANT 158->179)
