- Convert 10 workflows from pull_request_target to pull_request trigger - Create 3 reusable workflows with centralized test logic: - reusable-molecule-test-linux.yml - reusable-molecule-test-windows.yml - reusable-container-sensor-pull.yml - Add environment protection (molecule-testing) for PR secret access - Update actions/checkout to v5.0.1 (SHA pinned) - Fix psscriptanalyzer action pinning from main to v1.1 - Add CODEOWNERS file with falcon-scripts-cs-maintainers Security improvements: - Eliminates pull_request_target risks from fork PRs - Environment approval gates secret access for external contributors - All actions properly SHA-pinned with version comments - PR SHA passed explicitly to prevent confusion attacks
