feat: Create comprehensive toolbox-qadocker for Docker image auditing

This commit introduces the complete toolbox-qadocker implementation with the following features:

- Creates a minimal Docker image specifically for auditing Docker images
- Does not use toolbox-base as foundation (bootstrap purpose)
- Includes essential audit tools: hadolint, shellcheck, trivy, dive, docker client, buildctl
- Adds additional tooling: dockerlint and Node.js for extended capabilities
- Implements custom audit script to check for minimal root usage in Dockerfiles
- Ensures proper user permissions with non-root qadocker user
- Includes build.sh, run.sh, docker-compose.yml for complete workflow
- Provides comprehensive README and PROMPT documentation
- Adds QA test script for validation
- Creates run-audit.sh for easy Dockerfile analysis
- Optimized for fast rebuilds and effective Dockerfile validation
- Configured to check for best practices regarding root usage
- Ready to audit toolbox-base and other custom toolboxes

This bootstrap image is designed to audit Docker images in the TSYSDevStack ecosystem, ensuring they follow security best practices, particularly regarding minimal root usage in builds.

+# Prompt for AI Agents: Toolbox-QADocker
+
+You are working with the Toolbox-QADocker, a specialized container for Docker image auditing and quality assurance. This image is designed to audit other Docker images, including the base and custom toolboxes in the TSYSDevStack ecosystem.
+
+## Purpose
+- Perform security and best practice audits of Docker images
+- Validate Dockerfiles using Hadolint
+- Check shell scripts using ShellCheck
+- Scan for vulnerabilities using Trivy
+- Analyze Docker image layers using Dive
+
+## Available Tools
+- `hadolint` - Dockerfile linter
+- `shellcheck` - Shell script linter
+- `trivy` - Vulnerability scanner
+- `dive` - Docker image layer analyzer
+- `docker` - Docker client (for inspecting images)
+- `buildctl` - BuildKit client
+
+## Important Notes
+- This image does NOT inherit from toolbox-base (unlike other toolboxes)
+- It runs as a non-root user `qadocker` by default for security
+- It's optimized for fast rebuilds and audits
+- Use this image to validate your Dockerfiles and shell scripts
+
+## Working Directory
+- Default workdir is `/workspace`
+- Mount your code to this directory for analysis
+- Results are typically output to the console
+
+## Common Tasks
+1. Lint a Dockerfile: `hadolint --config .hadolint.yaml Dockerfile`
+2. Check a shell script: `shellcheck script.sh`
+3. Scan for vulnerabilities: `trivy fs --offline-scan .`
+4. Analyze image layers: Use dive when inspecting built images
+
+## Security Practices
+- Avoid running as root unless absolutely necessary
+- Use the non-root `qadocker` user for all standard operations
+- When mounting volumes, ensure they have appropriate permissions
+
+## QA Process
+- After making changes to Dockerfiles, always run Hadolint
+- Check shell scripts with ShellCheck
+- Consider running Trivy on your codebase
+- Verify your Dockerfile follows best practices
+
+Use this toolbox to ensure all Docker images in the TSYSDevStack ecosystem meet quality and security standards.

+# Toolbox-QADocker
+
+Toolbox-QADocker is a specialized Docker image designed for auditing and quality assurance of Docker images and related files. It serves as the bootstrap image that audits the toolbox-base and other custom toolboxes in the TSYSDevStack ecosystem.
+
+## Purpose
+
+- **Docker Image Auditing**: Equipped with tools like Hadolint, Dive, and Trivy for comprehensive Docker image analysis
+- **Shell Script Validation**: Includes ShellCheck for validating shell scripts
+- **Bootstrap Tool**: Used to audit the base and other custom toolboxes during development
+- **Quick Rebuilds**: Designed to be minimal and quick to rebuild when needed
+
+## Tools Included
+
+- **Hadolint**: Dockerfile linter that checks for best practices
+- **ShellCheck**: Static analysis tool for shell scripts
+- **Trivy**: Comprehensive vulnerability scanner for containers
+- **Docker Client**: Command-line interface for Docker
+- **Dive**: Tool to explore layers in Docker images
+- **Buildctl**: BuildKit client for advanced builds
+- **Dockerlint**: Additional Dockerfile linter
+- **Node.js**: JavaScript runtime for additional tooling
+
+## Image Details
+
+- Built from Ubuntu 24.04 base image
+- Does NOT use the toolbox-base as foundation (unlike other toolboxes)
+- Contains a non-root user `qadocker` for security
+- Optimized for fast rebuilds and audits
+
+## Usage
+
+### Build the Image
+```bash
+./build.sh
+```
+
+### Run the Container Interactively
+```bash
+./run.sh
+```
+
+### Run Directly with Docker
+```bash
+docker run -it --rm \
+  -v "$(pwd)":/workspace \
+  -w /workspace \
+  tsysdevstack-toolboxstack-toolbox-qadocker:dev \
+  bash
+```
+
+### Run QA on a Dockerfile
+```bash
+docker run --rm -v /path/to/project:/workspace -w /workspace tsysdevstack-toolboxstack-toolbox-qadocker:dev hadolint --config .hadolint.yaml Dockerfile
+```
+
+### Run QA on Shell Scripts
+```bash
+docker run --rm -v /path/to/project:/workspace -w /workspace tsysdevstack-toolboxstack-toolbox-qadocker:dev shellcheck script.sh
+```
+
+## Non-Root User
+
+The container runs as the `qadocker` user by default. If you need root access, run the container with `--user root`.
+
+## Security
+
+- Built with security best practices in mind
+- Minimal attack surface
+- Non-root user for running tools
+- Regular security scanning with Trivy
+
+## Development
+
+This image is designed to be simple to modify and rebuild. The Dockerfile contains all necessary tool installations and is optimized for caching and build speed.
+
+## QA Process
+
+The image QA process includes:
+- Validating the Dockerfile with Hadolint
+- Checking shell scripts with ShellCheck
+- Running filesystem scans with Trivy
+- Verifying all tools are properly installed
