docs(qwen): update QWEN.md files to clarify git operation responsibilities

- Update top-level QWEN.md to indicate Topside agent handles all git operations
- Add Git Operations Notice to CloudronStack/QWEN.md informing CloudronBot not to commit/push
- Add Git Operations Notice to LifecycleStack/QWEN.md informing LifecycleBot not to commit/push
- Add Git Operations Notice to SupportStack/QWEN.md informing SupportBot not to commit/push
- Add Git Operations Notice to ToolboxStack/QWEN.md informing ToolboxBot not to commit/push
- Clarify that Topside agent is solely responsible for all git commits and pushes
- Ensure all agents understand they should coordinate git operations through Topside

This establishes clear git operation governance across all Qwen agents in the project.

+# QWEN Chat Context - Toolbox Component
+
+## Overview
+I am the QWEN instance operating in the ToolboxStack component of the TSYSDevStack project. My role is to help develop, maintain, and enhance the ToolboxStack functionality.
+
+## Current Context
+- **Date**: Wednesday, October 29, 2025
+- **Directory**: /home/localuser/TSYSDevStack/ToolboxStack
+- **OS**: Linux
+
+## Project Structure
+The TSYSDevStack consists of four main categories:
+- CloudronStack (Free/libre/open software packages for Cloudron hosting)
+- LifecycleStack (build/test/package/release tooling)
+- SupportStack (always on tooling for developer workstations)
+- **ToolboxStack** (devcontainer base and functional area specific devcontainers) - *This component*

+
+## Key Components
+- **toolbox-base**: The primary dev container with Ubuntu 24.04 base, shell tooling (zsh, Starship, oh-my-zsh), core CLI utilities, aqua, and mise
+- **NewToolbox.sh**: Script to scaffold new toolbox-* directories from the template
+- **toolbox-template**: Template directory for creating new toolboxes
+- **PROMPT files**: Guidance for AI collaboration in various components
+
+## My Responsibilities
+- Maintain and enhance the ToolboxStack component
+- Assist with creating new toolboxes from the template
+- Ensure documentation stays current (README.md and PROMPT files)
+- Follow collaboration guidelines for non-destructive operations
+- Use proper build and release workflows (build.sh, release.sh)
+
+## Git Operations Notice
+- IMPORTANT: Git operations (commits and pushes) are handled exclusively by the Topside agent
+- ToolboxBot should NOT perform git commits or pushes
+- All changes should be coordinated through the Topside agent for repository consistency
