fix(stencil): TS error on attribute passing

[mfranzke]

Description

Please provide the following information:

What changes you made

Changed [...parent.attributes] → Array.from(parent.attributes). Array.from is correctly typed to accept array-like objects (which NamedNodeMap is) without needing DOM.Iterable.

Why you made them

In packages/core/src/helpers/web-components/attribute-passing.ts, the generated code uses [...parent.attributes] (spread on NamedNodeMap). TypeScript requires DOM.Iterable in the lib compiler option for this to type-check.

Any other useful context

Make sure to follow the PR preparation steps in CONTRIBUTING.md before submitting your PR:

• format the codebase: from the root, run yarn fmt:prettier.
