User flagged that all historical user bubbles render with the same
"now" clock after a chat reload — both messages in the screenshot
showed 9:01:58 PM despite being sent hours apart.
ChatTab.tsx:142 minted user messages with createMessage(...) which
calls new Date().toISOString() — fine for a freshly-typed message,
wrong for hydrated history. Every reload re-stamped all user bubbles
to the render moment, collapsing the visible chronology. The agent
path on line 157 already overrides with a.created_at; mirror that.
One-line fix (spread + override timestamp) plus a comment explaining
why the override is load-bearing so the next refactor doesn't drop it.
