Add GitHub Action with UV for pytest execution and status badge

[Copilot]

This PR implements a comprehensive CI/CD solution using UV (the modern Python package manager) to run pytest tests and display test status via a README badge.

Changes Made

🧪 Test Infrastructure

• Created tests/ directory with basic import tests to ensure core modules load correctly
• Added tests/test_imports.py with 5 test cases covering main package components
• Configured pytest settings in pyproject.toml for proper test discovery

🚀 GitHub Action Workflow

• Added .github/workflows/test.yml that leverages UV for fast dependency management
• Tests across Python 3.9, 3.10, 3.11, and 3.12 using matrix strategy
• Uses official astral-sh/setup-uv@v4 action with dependency caching
• Runs uv sync --all-extras --dev for lightning-fast dependency installation
• Executes pytest with verbose output and coverage reporting
• Integrates with Codecov for coverage tracking

📊 Status Badge

• Added test status badge to README.md header
• Badge shows real-time pass/fail status and links to workflow runs
• Provides immediate visibility into project health

⚙️ Configuration

• Enhanced pyproject.toml with pytest and coverage configurations
• Added appropriate test path discovery and coverage exclusions
• All tests pass locally and are ready for CI execution

[nitpick] Consider using explicit version format '3.10.x' instead of '3.10' to avoid potential ambiguity with semantic versioning interpretation in YAML.
