Executes Volt JavaScript and TypeScript test files in a QuickBEAM runtime.
This is the first, intentionally small, runner layer. It supports test files
that use global Vitest-like helpers (describe, test, it, beforeEach,
afterEach, and expect) provided by priv/ts/test/core.ts.
Test files may import helpers from volt:test; those virtual imports are
stripped before bundling because the runtime provides the helpers as globals.
Local relative JS/TS module graphs are bundled before execution.
