Real-model checks of the conversation screen found seven web problems, and the source scope help described a restriction the app does not apply yet.

Fixed

• A turn whose research is still running was drawn as "no answer · ask again"; it now shows only the question while the live progress block below it reports what is happening.
• A finished answer could stay folded; the newest finished turn now opens.
• Open follow-ups recorded as English "Resolve ..." now show the built-in criterion title in the screen language, or the person's own question.
• Closing a confirm, rename or delete dialog returned focus to the page body; focus now goes back to where it was.
• Live progress repeated the same place label and the same sentence; each is said once.
• The conversation token total was labelled as one research run; it now says "this conversation".
• Earlier rounds showed "no usage recorded" when the server simply does not send their usage; that line is left out.

Source scope help (5 languages): there is no screen yet for granting a task permission, and an unauthenticated local app reads project-owned sources whichever scope is chosen. The help now says so and recommends "Shared within this project". The hosted review environment, which asks for the scope first, shows the same help under the choice.

Web only, no Python changes. Includes the changes of #77; once #77 is merged only the changes above remain.

Validation: tsc -b, eslint, vitest 149 files (1,248 passed, 1 skipped), structure checks, vite build, mutation 19/19 caught. Real-model checks Q-90 to Q-92 passed; Q-93 screen checked with a fake provider response.
