Fixes SOU-2018

Problem

Users were seeing a "Network error" message displayed at the top of the Ask page after every question, even though the question would continue and succeed. The error appeared benign but was confusing and degraded the user experience.

Root Cause

The error banner visibility was only set to true when an error occurred, but was never automatically hidden when the error state was cleared by the AI SDK. This caused stale error banners to persist even after:

• A new request started successfully (the AI SDK explicitly clears errors when starting a new request)
• A transient error was resolved

The problematic code:

useEffect(() => {
    if (error) {
        setIsErrorBannerVisible(true);
    }
}, [error]);

This effect only ran when error changed to a truthy value, but did nothing when error became undefined (cleared).

Solution

Changed the effect to properly synchronize banner visibility with the error state:

useEffect(() => {
    setIsErrorBannerVisible(!!error);
}, [error]);

Now:

• When error is truthy → banner is visible
• When error is falsy (undefined/null) → banner is hidden

This ensures that transient errors that get cleared by the AI SDK (e.g., when a new request starts) no longer leave lingering error banners.

Testing

• Ran linter: yarn workspace @sourcebot/web lint ✅
• Ran web package tests: yarn workspace @sourcebot/web test ✅ (1424 tests passed)
