修复即将推出

> <https://github.com/discourse/discourse/pull/42524>
>
> Previously, streamed structured-output chunks in the AI helper were appended onl…y when \`present?\`, so whitespace-only deltas (e.g. an escaped \`\\n\\n\` between paragraphs) were consumed from the parser buffer and silently dropped, collapsing multi-paragraph proofread results into a single paragraph (regressed in #42442; the same pattern existed in \`ReportRunner\` and \`ChatThreadTitler\`).
> 
> This change appends any non-nil, non-empty chunk, preserving paragraph breaks and spaces, and adds a regression spec streaming whitespace-only deltas.
