Current IPA on server is v261013-3 (previous beta).
New v261013-4 is being built — GitHub CI runner is queued.
Key fixes in v261013-4:
1. Image crash fix — custom base64 decoder (no iOS 7+ API)
2. Deep thinking — removed Reasoning:/Answer: prompt prefixes
3. Performance — throttled reloadData during streaming

If the new IPA is not here by 11:30, use v261013-3 from GitHub:
