✨ Set up Copilot instructions for homebridge-august repository

[Copilot]

This PR implements comprehensive GitHub Copilot coding agent instructions for the homebridge-august repository, following the best practices documented in GitHub's Copilot coding agent guidelines.

What's Added

A detailed .copilot/instructions.md file that provides:

• Repository Overview: Clear description of the Homebridge plugin architecture and purpose
• Development Workflow: Complete guide for building, testing, linting, and documentation
• Coding Standards: TypeScript/ESLint configuration details and code style requirements
• Homebridge Specifics: Platform patterns, HAP services, and plugin lifecycle management
• August/Yale Integration: API authentication flow and device management patterns
• Testing Guidelines: Vitest configuration and testing best practices
• Security Considerations: Credential handling and validation requirements

Key Features

The instructions cover the unique aspects of this repository:

• TypeScript with ES2022 and bundler module resolution
• Dynamic platform plugin pattern (not accessory plugin)
• Custom Homebridge Config UI X integration
• August/Yale API authentication with validation codes
• ESLint with Antfu configuration and custom rules
• Vitest testing framework with coverage support

This will help Copilot provide more accurate and contextually appropriate code suggestions when working on this Homebridge plugin.

Work resumed! I've set up comprehensive Copilot instructions for the homebridge-august repository following GitHub's best practices. The .copilot/instructions.md file includes detailed guidance for the TypeScript/Homebridge architecture, development workflow, coding standards, August/Yale API integration patterns, and testing guidelines. All existing lint, build, and test commands continue to work correctly. (a59e37f)
