refactor(dspy): extract templates to separate module (#3)

- Create dspy/templates.py with Cairo contract and test templates:
  - CONTRACT_TEMPLATE and CONTRACT_TEMPLATE_TITLE
  - TEST_TEMPLATE and TEST_TEMPLATE_TITLE

- Update document_retriever.py to import from templates module:
  - Reduces file size by ~290 lines
  - Separates template content from retrieval logic

- Update imports in:
  - dspy/retrieval_judge.py
  - tests/unit/test_retrieval_judge.py

This improves maintainability by keeping template content
separate from the document retrieval implementation.
