Summary

This is the batch re-record of the size ledger after #4620, #4621, #4604 and #4630 merged. The numbers come from next's push Size run at f8080f3 (head job 125582643125). Hello world is unchanged at 9,974 B, and its 9.98 KB cap is untouched.

Size-Exception: frozen floors re-recorded after the batch. #4621's For-row growth (+35 to +44 B minified on the hydrating, base server components, live server components and renderToString floors) was accepted by the maintainer. The live server components floor cap goes from 39.76 KB to 39.77 KB.

How did you test this change?

• The numbers are CI's measurements from next's push Size job, not local ones.
• Ran prettier on scripts/size.

_{Bundled with Rolldown (what Vite ships), brotli q11, decimal KB. A scenario fails only when it is over its brotli cap and its minified size is more than 20 B over the minified recorded with the cap; over the cap within that allowance is brotli layout noise and passes with a warning. Caps and their recorded minified in scripts/size/scenarios.js; the floor and page caps in floor-caps.json are frozen (lower only, or Size-Exception: in the PR body). npm run ratchet lowers caps per RC; it never raises one (scripts/size/README.md).}
