A look keeps its page's size: scrollWidth, scrollHeight, innerWidth and innerHeight are stored on it and read back #10205

A look now keeps its page's size, so you can answer "does this page scroll sideways" from the row without starting a browser.

• Migration: 20261109180000-a-look-keeps-its-page-size.ts adds four nullable integer columns to look: scroll_width, scroll_height, inner_width and inner_height. Its pin file is committed with it.
• Reading: toLook in src/core/looks.ts returns size: { scrollWidth, scrollHeight, innerWidth, innerHeight }. When any of the four is null the look has no size key at all.
• Writing: recordLook takes an optional size. A retake overwrites the stored size, so a retake without one clears the old one. In src/looks/service.ts the successful-capture save passes along the size the capture recorded. A look without one stores nulls and does not fail.
• Tests: test/look-page-size.test.ts has five cases: with a size, without, a retake that clears it, a row inserted before the migration, and a row with only some columns set. No browser starts.
• Checks: The new test, scripts/gate.ts and tsc --noEmit pass. Three Chromium tests in test/looks.test.ts fail in this sandbox, and fail the same way with my change stashed, because the sandbox blocks the browser's socket. I didn't run the rest of the suite; the forge's check runs it on push.

I did not touch the capture itself, the pages or the API, and nothing displays the size yet. Failed captures and attached looks store nulls.

To try it, call recordLook(db, { ..., size }) and then getLook(...).

Closes #10202
