feat: add learning guide & website badge

- Add "Visit Website" badge to README.md (prominent, top position)
- Add learning-with-ai.md guide for junior developers (~900 lines)
  - UVAL Protocol, dependency patterns, 30-day progression plan
- Add 3 learning templates (55 total):
  - examples/claude-md/learning-mode.md
  - examples/commands/quiz.md
  - examples/hooks/bash/learning-capture.sh
- Fix template count: 52 → 55 (was incorrectly showing 56)
