feat(registry): add parallax-zoom and parallax-unzoom components

Two companion components inspired by the eBay Playbook hero transition:

- parallax-zoom: center card scales up to fill the frame while siblings
  parallax outward. Single CSS variable (--pz-progress 0→1), fully
  seekable and deterministic.

- parallax-unzoom: the reverse — focus card starts at full-frame scale
  and shrinks back into its grid position while siblings parallax inward.
  Uses --pu-progress with the pu prefix to avoid variable collisions when
  both components live in the same composition.

Designed to chain: zoom INTO a card in scene 1, unzoom OUT of it in
scene 2 to reveal a fresh grid underneath.

Includes demo compositions, registry manifests, and catalog pages.
Preview assets rendered and uploaded to CDN.
