Add plugin hook filter to `transform` function

Hey 👋

I saw that the custom `transform` hook does not use a hook filter yet which would improve build perf as it reduces the amount of JS <> Rust comms overhead.

Locate the custom transform hook in the TypeScript plugin and read the linked ecosystem issue #171 first. Confirm the hook filter applies to transform processing, while preserving React ref-prop transformation and reducing unnecessary JS ↔ Rust communication.
