test: use it.fails() pattern for issue #4000 reproduction test

Update the test to use Vitest's it.fails() pattern to keep CI green
while still documenting the bug reproduction. The test:
- Currently fails with 'syntax error at end of input' (expected behavior)
- Will pass because it's marked as .fails()
- Will alert us when the bug is fixed (test will fail because it expects to fail but succeeds)

This is the standard pattern for regression tests that capture current bugs.
