test-runner

Run a project's tests at the right scope — changed-only, focused, full, type-check, or e2e — then, on failure, read the output and traces, apply a minimal fix, and rerun until green or blocked. Detects the test runner and package manager from the repo. Use when the user asks to run tests, run the suite, run smoke/e2e tests, type-check, check the build compiles, fix failing tests, or runs /tests.
