transform styled dom component usage for improved performance

[jantimon]

This is a nice to have performance optimizations by transforming the following code:

From:

import { styled } from "next-yak";
const button = styled.button`...`

To:

import { __yak_button } from "next-yak/internal";
const button = __yak_button`...`

Benefits:

1. Reduces runtime overhead by eliminating proxy object property lookup
2. Enables better tree-shaking, potentially reducing bundle size
3. Improves minification efficiency

This optimization could lead to faster execution and smaller bundle sizes, especially beneficial for large applications with many styled components.
