Ramnique Singh c81d3cb27b surface silent runtime failures as error events
AgentRuntime.trigger() wrapped its body in try/finally with no outer
catch. An inner catch around the streamAgent for-await only handled
AbortError and rethrew everything else. Call sites fire-and-forget
trigger (runs.ts:26,60,72), so any thrown error became an unhandled
promise rejection. The finally still ran and published
run-processing-end, but nothing told the renderer why — the chat
showed the spinner, then an empty assistant bubble.

Provider misconfig, invalid API keys, unknown model ids, streamText
setup throws, runsRepo.fetch or loadAgent failing, and provider
auth/rate-limit rejections on the first chunk all hit this path on a
first message. All invisible.

Add a top-level catch that formats the error to a string and emits a
{type: "error"} RunEvent via the existing runsRepo/bus path. The
renderer already renders those as a chat bubble plus toast
(App.tsx:2069) — no UI work needed.

No changes to the abort path: user-initiated stops still flow through
the existing inner catch and the signal.aborted branch that emits
run-stopped.
