refactor(rust-bridge): require the native extension (#48852)
* refactor(rust-bridge): require the native extension

_native ships in every wheel and the sdist will not install without it, yet the bridge loaded it optionally and carried None paths that could fail open for fork safety, exception mapping and OTLP errors. Delete loader.py and import _native directly. Tests inject a fake module through NativeBinding(source=...) or with_source() instead of patching the loader

The install smoke checks now verify the compiled module, and tests fail instead of skipping when _native is missing. The interactions spec canary installs the project so it has the extension
