Problem

Sentry issue ELECTRON-P — 105 occurrences.

In ModelModalContent.tsx, the health check creates a responsePromise with a 30s timeout. If the timeout fires while sendMessage.invoke() is still pending, the rejection is unhandled because await responsePromise hasn't been reached yet.

Root Cause

Race condition: responsePromise rejects (timeout) → but await responsePromise at line 311 hasn't been reached yet because await sendMessage.invoke() at line 304 is still in progress → unhandled promise rejection.

Fix

Add responsePromise.catch(() => {}) immediately after creation to mark the rejection as handled. The actual error is still caught by await responsePromise in the outer try-catch.
