Add dedicated test.yml workflow for PR validation

[Copilot]

No CI workflow ran tests on pull requests — the only automated test execution was buried inside a custom composite action used by daily agent workflows, invisible to PR checks.

Changes

• .github/workflows/test.yml (new) — Runs on push/pull_request to main using astral-sh/setup-uv@v4 + uv sync --all-extras + uv run pytest tests/ -v --tb=short. Matches the documented developer workflow. Minimal contents: read permissions.

  - uses: astral-sh/setup-uv@v4
    with:
      enable-cache: true
  - run: uv python install 3.13
  - run: uv sync --all-extras
  - run: uv run pytest tests/ -v --tb=short

• README.md — Adds a Tests badge alongside the existing Sync/Bandit/Codacy badges.

<issue_title>[Code Quality] Add dedicated test.yml workflow for PR validation</issue_title>
<issue_description>### Description

The repository has a comprehensive test suite (18 test files, 5,358 lines) but lacks a dedicated workflow to run tests on pull requests. Tests currently run via a custom action in daily workflows, but not for PR validation.

Problem

From the QA Report (#337):

• Test execution happens via .github/actions/daily-perf-improver/build-steps/action.yml
• No dedicated test.yml workflow for PR validation
• Contributors can't see test results before merging
• No automated test enforcement on pull requests

Current State

• Tests exist in tests/ directory (18 files)
• Tests can be run locally with uv run pytest tests/
• CI workflows (sync.yml, bandit.yml) don't include test execution for PRs
• Custom actions have tests embedded but not standardized

Suggested Changes

1. Create .github/workflows/test.yml with:

   • Trigger on PR and push to main/master
   • Python 3.13 environment setup
   • Dependency installation via uv sync --all-extras
   • Test execution: uv run pytest tests/ -v --tb=short
   • Test result reporting in PR comments

2. Configure test workflow options:

   • Run on multiple Python versions (3.13, 3.14) if needed
   • Enable parallel test execution: pytest -n auto
   • Code coverage reporting (pytest-cov)
   • Fail fast on first test failure for faster feedback

3. Add workflow status badge to README.md

Files Affected

• .github/workflows/test.yml (new file)
• README.md (add test workflow badge)
• Consider updating branch protection rules to require tests

Success Criteria

• ✅ Tests run automatically on every PR
• ✅ Test results visible in PR checks
• ✅ Workflow uses consistent Python version (3.13+)
• ✅ Test execution time < 2 minutes (with parallel execution)
• ✅ Clear failure messages when tests fail

Priority

High - Essential for maintaining code quality on pull requests

Effort Estimate

30 minutes (create workflow, test configuration, add badge)

Implementation Notes

Follow the memory pattern from .github/workflows/test.yml examples:

• Use astral-sh/setup-uv@v4
• Run uv sync --all-extras
• Execute uv run pytest tests/ -v

This matches the documented developer workflow and ensures consistency.

Pull request overview

This pull request adds a dedicated test workflow for automated PR validation, addressing a gap where the comprehensive test suite (18 test files) was not being run on pull requests. Previously, tests only ran via a custom composite action in daily agent workflows, invisible to PR checks.

Changes:

• Creates a new .github/workflows/test.yml workflow that runs on push/PR to main using uv for dependency management and pytest for test execution
• Adds a Tests badge to README.md alongside existing CI badges

README.md	Adds Tests workflow badge to display test status

[Copilot]

The test command is missing the -n auto flag for parallel test execution. The existing custom action in .github/actions/daily-perf-improver/build-steps/action.yml uses pytest tests/ -n auto -v to run tests in parallel, and the repository includes pytest-xdist>=3.0.0 in dev dependencies specifically for this purpose. Running tests in parallel will significantly reduce CI execution time, especially as the test suite grows (currently 18 test files).
