test(web): re-record the subagent goldens against a rebuilt client

The child session now shows the preset badge its parent shows, which is the
visible consequence of recording the composition it runs. The first recording
of these two goldens was taken against a dist built before the master merge,
so it captured the fallback Chinese label instead of the English one
`newEnglishPage` pins — the web lane replays the BUILT client, and a stale
build reads as a product difference. Re-recorded after `pnpm run build`.
