feat: Add Community Forum Integration & E2E API Tests (#309, #337)

Summary

This PR implements two critical features for AstroML:

  1. GitHub Discussions API Integration (#309) - Community forum/discussion integration with real-time fetching, caching, search, and user reputation tracking
  2. End-to-End API Test Suite (#337) - Comprehensive E2E tests covering critical user journeys with Docker containerization, CI/CD integration, and flaky test detection

Issues Closed

Closes #309 Closes #337

Environment Variables Required

For GitHub Discussions integration:

GITHUB_TOKEN=<your-github-token>
GITHUB_OWNER=Traqora
GITHUB_REPO=astroml

For E2E tests:

DATABASE_URL=postgresql://test:test@localhost:5432/astroml_test
REDIS_URL=redis://localhost:6379
API_BASE_URL=http://localhost:8000

CI/CD Workflow

The E2E test workflow:

  1. Checks out code
  2. Sets up Python environment with cached dependencies
  3. Starts PostgreSQL and Redis services
  4. Builds and starts API server
  5. Waits for API health check
  6. Runs E2E tests with coverage
  7. Generates test reports (XML, JSON, HTML)
  8. Uploads artifacts to GitHub
  9. Publishes results to PR comment
  10. Detects and reports flaky tests
