feat: Add Codecov integration to release workflow

[jeremyeder]

Description

Add Codecov integration to the release workflow to upload test coverage reports, matching the pattern used in the platform repository.

Requirements

• Run test suite with coverage on new releases
• Upload coverage to Codecov.io
• Use CODECOV_TOKEN from repository secrets
• Flag coverage as "release" for tracking
• Don't fail CI if Codecov upload fails (fail_ci_if_error: false)

Implementation Steps

1. Sign up at https://codecov.io
2. Add CODECOV_TOKEN to GitHub repository secrets
3. Add workflow steps in .github/workflows/release.yml:

- name: Run tests with coverage
  if: steps.check_release.outputs.new_release == 'true'
  run: |
    echo "🧪 Running tests with coverage..."
    pip install -e .
    pytest --cov=src/agentready --cov-report=xml --cov-report=term-missing

- name: Upload coverage to Codecov
  if: steps.check_release.outputs.new_release == 'true'
  uses: codecov/codecov-action@v5
  with:
    token: ${{ secrets.CODECOV_TOKEN }}
    files: ./coverage.xml
    flags: release
    name: release-coverage
    fail_ci_if_error: false

Benefits

• Track coverage trends over releases
• Public coverage badge for README
• Validates test quality
• Matches platform repo pattern

References

• Codecov GitHub Actions
• Codecov Documentation
• Platform repo implementation: https://github.com/ambient-code/platform

Triage Update - Valid Enhancement, Blocked 📋

Status: Valid - Low Priority (Blocked by #103)
Priority: P3 (blocked by test coverage work)
Recommended Labels: enhancement, backlog, blocked-by-#103, codecov

Validation Against Current Codebase

• ✅ Valid enhancement - coverage reports exist
• ✅ Release workflow exists in .github/workflows/release.yml
• ⚠️ Lower priority than fixing actual test coverage

Recommendation

Block on Issue #103 completion.

Don't advertise coverage until we have something to be proud of:

1. First: Achieve 70%+ coverage (Issue [P0] Improve Test Coverage to Meet 90% Threshold #103)
2. Then: Add Codecov integration to show progress
3. Goal: Hit 90% coverage before promoting it

Current strategy: Fix the problem first, then measure it publicly.

Move to backlog, revisit when coverage hits 70%.
