Subject: Add remaining helper functions for eventloop tests
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Implement makeEnterNameEvent for NameEvent syscalls (rename, link, symlink)
- Implement makeEnterNullEvent/makeExitNullEvent for NullEvent syscalls (sync, io_uring_setup)
- Implement makeEnterDup3Event for Dup3Event syscalls (dup3)
- Update TODO.md to mark helper functions as completed

All helper functions are now implemented and tests pass successfully.
This provides the foundation for comprehensive syscall testing across
all event types supported by ior.
