Add comprehensive GitHub Copilot instructions for WoW addon development

[Copilot]

This PR adds a comprehensive AGENTS.md file that provides GitHub Copilot coding agents with detailed instructions for working effectively in this World of Warcraft addon codebase.

What's Included

The instructions cover the complete development workflow for this dual-addon ecosystem:

• WagoUI: The pack installer addon (27 files, ~0.4s validation time)
• WagoUI_Creator: The pack creator addon (22 files, ~0.4s validation time)
• WagoUI_Libraries: Shared libraries with 35+ addon profile modules

Key Features

Validated Commands: All 13 command examples have been tested and work correctly:

• Syntax validation using luacheck (0.8s for full codebase, NEVER CANCEL)
• Individual addon validation (0.4s each)
• Project structure verification
• File location guidance

Build Process Clarity:

• GitHub Actions only builds (BigWigsMods packager)
• 5-15 minute build times with explicit "NEVER CANCEL" warnings
• Proper timeout recommendations (30+ minutes for builds)

Developer Workflow:

• Syntax-first continuous validation approach
• Key file locations (TOC files, slash commands, constants)
• WoW API global handling with .luarc.json integration
• Troubleshooting guide for common Lua/WoW API issues

Manual Testing Scenarios:
Since this is a WoW addon that can't run standalone, the instructions provide validation approaches for:

• Slash command functionality (/wago, /wui, /wagoui)
• UI frame structure verification
• Database schema validation
• Error handling verification

All instructions follow an imperative tone ("Always run", "Check that", "Verify") and include precise timing expectations to prevent premature cancellation of operations.

Fixes #28.
