Execute Phase 2 - Core API Integration from PROMPT.md.

Phase 1 is complete. Now implement Phase 2.

Read PROMPT.md for API specifications.
Read prd.json for Phase 2 features.

Phase 2 tasks:
1. Claude API client with Anthropic SDK
2. Perplexity API client with fetch
3. Architecture classification prompt and parser
4. Research query generation
5. Tests for all API clients

API Integration notes:
- Use environment variables for API keys during testing
- Implement retry logic with 3 attempts and exponential backoff
- Handle rate limits gracefully
- Parse JSON responses safely

For each feature:
1. Write tests first using mocked API calls
2. Implement the feature
3. Verify: npm run build && npm run test && npm run lint
4. Update prd.json when feature passes
5. Commit and log progress

When ALL Phase 2 features pass:
Output <promise>PHASE_2_COMPLETE</promise>

If blocked:
Output <promise>PHASE_2_BLOCKED</promise>
