refactor: convert IO from singleton instance to static class with metaclass native methods

Browse Source 
Replace the global `io` singleton object with a static `IO` class, moving the `write` native from the instance to the metaclass. Update all benchmark, example, and test files to use `IO.write()` instead of `io.write()`.
