[WIP] Add configuration for multiple repository runner

[Copilot]

Self-Hosted Runner Configuration for Raspberry Pi

Overview

Configure GitHub Actions workflows to effectively use a self-hosted Raspberry Pi runner across multiple repositories with proper job queuing and container parallelization.

Implementation Plan

• Analyze existing workflow structure
• Create comprehensive runner configuration workflow
• Add concurrency control for job queuing
• Implement parallel container execution example
• Create documentation for multi-repository runner setup
• Add runner health check workflow
• Create example workflows for different use cases
• Document best practices and limitations

Key Features to Implement

1. Concurrency Control: Queue jobs when runner is busy
2. Container Parallelization: Run multiple containers in parallel when resources allow
3. Multi-Repository Support: Documentation for registering runner in multiple repos
4. Resource Management: Monitor and manage runner resources
5. Job Prioritization: Handle critical jobs first
