Create custom instructions for GitHub Copilot

[josecelano]

To improve the quality and relevance of suggestions from GitHub Copilot, we should create a repository-specific custom instructions file. This file will provide Copilot with essential context about our project's goals, technical stack, and conventions.

Following the official GitHub documentation, we will create a .github/copilot/instructions.md file to guide the LLM's behavior when working within this repository.

Action Items

1. Create the necessary directory structure: .github/copilot/.
2. Create a new file named instructions.md within the .github/copilot/ directory.
3. Populate instructions.md with key information about this repository, including:
   • The overall purpose: providing a demo setup for the Torrust Tracker.
   • The current major initiative: migrating the tracker to a new infrastructure on Hetzner.
   • The chosen architecture: a native (non-Docker) tracker binary with supporting services (Nginx, Prometheus, MySQL) running in Docker.
   • The desired persona for interactions: an experienced open-source developer and system administrator.
   • Project conventions, such as the use of Conventional Commits for commit messages.
