Add comprehensive testing infrastructure
This commit adds a complete testing setup for the prettier_action: - Adds BATS (Bash Automated Testing System) testing framework - Creates unit tests for _git_setup() and _git_changed() functions - Creates plugin validation tests to ensure proper prettier plugin format - Creates integration tests for end-to-end workflows - Adds automated test runner script (tests/run_tests.sh) - Adds GitHub Actions workflow for CI/CD testing - Includes ShellCheck linting for bash scripts - Updates README with comprehensive testing documentation - Updates .gitignore to exclude test artifacts Test coverage includes: - Git configuration with different identity modes - File change detection - Plugin name validation (official, community, and scoped formats) - Working directory handling - node_modules cleanup - package-lock.json restoration - only_changed file filtering - Dry run behavior The test suite can be run locally with ./tests/run_tests.sh and runs automatically on all pushes and pull requests.
