Tdd Gate

Test-Driven Development enforcement hook. Blocks editing production code files (.cs, .py, .ts, .go, .rs, .rb, .php, .java, .kt, .swift, .dart) unless a corresponding test file exists. Forces the TDD workflow: write tests first, then implement. Automatically skips config files, migrations, DTOs, test files themselves, and infrastructure files. Looks for test files with common naming patterns (MyClassTest.ext, my-class.test.ext, my_class_test.ext, test_my_class.ext). Inspired by pm-workspace's Spec-Driven Development methodology.
