Rewrite tests in Python with cross-platform support

[Copilot]

Plan: Rewrite Tests in Python and Add Multi-Platform Support

• Analyze current BATS test structure in tests.bat
• Create Python test framework using unittest
• Rewrite test cases from BATS to Python
  • Test: ensuring .meta is committed
  • Test: ignoring assets file which starts with dot
  • Test: renaming directory
• Add cross-platform support for test execution
  • Ensure tests work on macOS
  • Ensure tests work on Windows with PowerShell
  • Handle git execution via Scoop mingit on Windows
• Update CI workflow to test on multiple platforms
  • Add macOS runner
  • Add Windows runner with Scoop mingit setup
• Create test runner script for local testing
• Update documentation with new test instructions
• Update README.md with testing section
• Make git run hooks automatically instead of manually
• Delete TESTING.md per requirement
• All tests passing locally
• Remove useless chmod step from workflow
• Delete old bats workflow file
• Fix Windows CI failure (PermissionError in tearDown)
• Delete deprecated tests.bat file

Summary

Successfully rewrote the test suite from BATS to Python with the following improvements:

1. Cross-platform support: Tests now work on Linux, macOS, and Windows
2. Automatic hook execution: Git runs hooks automatically during commits (not manual execution)
3. Windows Scoop mingit support: Tests handle git installed via Scoop mingit on Windows
4. GitHub Actions CI: Multi-platform testing workflow for ubuntu-latest, macos-latest, and windows-latest
5. Clean implementation: All 3 test cases passing with realistic git workflow simulation
6. Removed unnecessary steps: Cleaned up workflow by removing chmod step (Python doesn't require executable flag)
7. Removed old BATS files: Deleted deprecated bats.yml workflow and tests.bat file
8. Windows file permission handling: Fixed tearDown to handle Windows readonly git objects

Original prompt

Test hooks for macOS and Windows. Rewrite tests in Python. In Windows, Use PowerShell to execute git installed via Scoop mingit package.

Removed in e0455da. Python doesn't need the executable flag to run with python test_hooks.py.
