f87c143eb4 feat(automation): Automation::render_pixels returns a page as RGBA, without the PNG round trip (#2318)
`page_render` only returns PNG. A host that paints the page straight onto a canvas (a browser, a
GPU texture) encodes a PNG only to decode it again, on every scroll. `render_pixels(doc, page,
scale)` uses the same renderer and the same per-document cache as `page_render` and returns the
width, the height and the RGBA pixels; `scale` is pixels per point (1.0 = 72 dpi). `Pixels` is
re-exported so the caller can name the type.

It validates like the tool does: the scale must be finite and within the tool's dpi limit, the page
must exist (1-based), and the document must be open. The test checks the size agrees with
`page_render` at 72 dpi, the buffer is RGBA, the scale doubles the width, and each refusal.

This is an embedder API, not a user-facing feature, so it has no tool and no parity entry.
