/**
 * Focused test runner: reuses the full runner's setup (built static assets +
 * stripe-mock, via the shared test harness) but runs only the test files
 * passed as arguments and skips coverage enforcement. This lets a fresh
 * checkout run a subset of the suite without manual preparation or leftover
 * build artifacts.
 *
 *   deno task test:files test/integration/server-balance-webhook.test.ts
 *   deno task test:files test/shared/dates.test.ts --filter "formats date"
 *
 * Arguments are forwarded verbatim to `deno test`, so paths, directories, and
 * flags such as `--filter` all work. At least one argument is required.
