Zoo Code Files

[3.88.0]

• ✨ Provider and model support: Use Grok Build and improved custom-model support. This release also fixes Bedrock model limits and sends the Codex verbosity setting.
• 🧭 Task reliability: This release fixes cancellation handling, tool-turn continuation, and task-message saving.
• ⚡ Faster editing and chat: File writes no longer use artificial delays by default. Chat messages carry less file data, and code actions reach the last active chat.
