Add AI Assistant Guide for repository usage

[Copilot]

User asked "what can you do? how I give you context" - this adds documentation answering both questions.

Changes

• Created docs/AI_ASSISTANT_GUIDE.md: Comprehensive guide covering:

  • AI capabilities for this dotfiles repo (Ansible roles, Nix configs, scripts, docs, troubleshooting)
  • How to provide effective context (specificity, problem description, environment details, file references)
  • Examples of well-defined tasks across different categories
  • Repository structure and common workflows
  • Limitations and constraints

• Updated README.md: Added AI Assistant section linking to the guide

Example Task Format

The guide demonstrates how to phrase requests effectively:

✅ Good: "Add a new Ansible role to install and configure Docker with docker-compose"
❌ Poor: "Fix Docker"

Includes concrete examples for software installation, documentation updates, script creation, configuration fixes, and role enhancements.

Original prompt

what can you do? how I give you context
