Subject: [PATCH] fix(register): pass imports with import attributes through to
 the default loader

The resolve hook already defers to nextResolve when import attributes are
present, but the load hook still compiled the resolved source as TypeScript.
This breaks text imports (`with { type: 'text' }`, Node.js 26.5+ behind
--experimental-import-text): the raw text was fed to swc and failed to parse.

Skip the load hook when import attributes are present so the default loader
handles the module, mirroring the existing resolve behaviour.
