robobun 5617b92a5a test: refactor spawnSync to spawn with describe.concurrent (#25849) ...

## Summary

- Refactor 16 test files to use async `Bun.spawn` instead of
`Bun.spawnSync`
- Wrap tests in `describe.concurrent` blocks for parallel execution
- Use `await using` for automatic resource cleanup

## Performance Improvement

| Test File | Before | After | Improvement |
|-----------|--------|-------|-------------|
| `node-module-module.test.js` (28 tests) | ~325ms | ~185ms | **43%
faster** |
| `non-english-import.test.js` (3 tests) | ~238ms | ~157ms | **34%
faster** |

## Files Changed

- `test/cli/run/commonjs-invalid.test.ts`
- `test/cli/run/commonjs-no-export.test.ts`
- `test/cli/run/empty-file.test.ts`
- `test/cli/run/jsx-symbol-collision.test.ts`

## Test plan

- [x] All refactored tests pass with `USE_SYSTEM_BUN=1 bun test <file>`
