Fix: Refactor loader tests to use /tmp directory helper
Changes: - Create tests/helpers/test-loader.js with setupLoaderTestDir helper - Use /tmp/test-data for all file-based loader tests (Docker compatible) - Refactor JsonFileModelLoader tests to use setupLoaderTestDir - Simplify beforeEach/afterEach cleanup with helper methods - Add getTestFilePath method for flexible file path handling - Fix linting issues (unused vars, conditional expects)
