Add GitHub Copilot instructions for CBWIRE repository

[Copilot]

Configures GitHub Copilot coding agent instructions per best practices to provide context-aware assistance for this CFML/BoxLang/ColdBox module.

Changes

• Added .github/copilot-instructions.md (245 lines) documenting:
  • CFML/BoxLang/ColdBox framework conventions and supported engines (Lucee 5+, Adobe CF 2021+/2023+, BoxLang 1+)
  • Code style: script-based syntax, tab indentation, 120-char lines, double quotes
  • CommandBox package manager and cfformat configuration
  • TestBox testing framework with multi-engine test requirements
  • Wire component patterns and lifecycle
  • Module structure, configuration settings with defaults
  • Dependency injection and common patterns

Context

Enables Copilot to understand CFML and BoxLang syntax, ColdBox framework patterns, and project conventions when generating suggestions. Example wire component pattern documented:

component extends="cbwire.models.Component" {
    data = {
        "message": "Hello World"
    };
    
    public function updateMessage( required string newMessage ) {
        data.message = newMessage;
    }
}
