Architecture fix for long-running tool execution: 1. ClaudeCliProtocol: Two-tier idle timeout - Chat mode: 45s (detect API hang/silent rate limit) - Tool execution mode: 5min (Bash long tasks like pip install) - Automatically switches on tool_use_start / content_block_stop events 2. Provision API: POST /templates/:templateId/provision - Runs shell commands directly via child_process.exec - Bypasses Claude ACP entirely (no idle timeout issue) - 10min per-command timeout, security blocklist - Frontend button with prompt for custom commands 3. Template UI: Added 🔧 安装依赖 button (teal)
