What was wrong

After OpenBot quit while its engine machine was stopped, the next launch showed "That didn't finish: OpenBot had trouble shutting down last time." over the "OpenBot is stopped" card. The card stayed through Start and through every Retry. When that Start stopped as well (the engine was down, "Getting OpenBot ready" failed with "The software OpenBot runs on isn't running. Retry to start it."), the old notice read as the reason this run stopped.

The cause: the setup window keeps what last_failure returned at launch as its recovery failure, and cleared it only when a Start succeeded, on Stop, or on a provider change. A Start that stopped in the local sequence never reached any of those.

The fix

The notice read at launch is about the last run, so it goes as soon as a Start runs. Only that notice is cleared: a failure of the new Start still shows, in its row and in the card, as before.

Tests

• New UI test the last shutdown's notice goes once Start runs, and a Start that stops says only why: launch with the shutdown notice, press Start with the engine down, then Retry once it answers. Failed before the fix (the notice was still on screen after Start stopped), passes after.
• bun test desktop/src (416 pass), bun run --cwd desktop typecheck, bun run format:check, bun run lint.
• Real-product check on the Mac: quit OpenBot with the engine machine stopped, relaunch, Start, and the notice is gone.
