fix(tests): resolve CI failures on Windows and formatting issues

- Convert esm-imports.test.mjs to vitest (was using node:test API)
- Fix formatting in esm-imports test (multi-line assert.ok)
- Replace fs.rm with safeDelete in json tests for Windows compatibility
  - Fixes EPERM errors when cleaning up temp directories on Windows
  - Uses @socketsecurity/lib/fs safeDelete for cross-platform safety
