Add GitHub Copilot instructions and VSCode settings with ember-mcp MCP server integration

[Copilot]

Added .github/copilot-instructions.md to provide Copilot with context about this repository and instruct it to use the ember-mcp MCP server when working with Ember.js code. Also added .vscode/settings.json to automatically configure the local MCP server for development.

Key Instructions

• MCP Server Configuration: Local and production setup examples for the ember-mcp server
• Tool Usage Guidance: High-level guidance on when to use the 7 MCP tools with references to README for details
• Codebase Architecture: Overview of index.js, lib/ services, testing with Vitest, and MCP protocol implementation
• Development Workflows: Package manager detection emphasis, testing commands, and key patterns

VSCode Settings

Added .vscode/settings.json to automatically wire up the local MCP server for development work:

• References .github/copilot-instructions.md for Copilot guidance
• Configures local ember-mcp server using workspace-relative path
• Uses VSCode's servers key (not mcpServers like Claude Desktop)

The instructions file was streamlined from 232 to 80 lines by removing information that can be obtained through other means (README.md, MCP tools, codebase exploration) and focusing on unique codebase-specific guidance.

Configuration Example

{
  "mcpServers": {
    "ember": {
      "command": "npx",
      "args": ["-y", "ember-mcp"]
    }
  }
}

The setup emphasizes always detecting the project's package manager before suggesting commands and using the MCP tools for Ember.js guidance.

Removed duplicated information. Streamlined from 232 to 80 lines by:

• Removing detailed tool descriptions (already in README.md)
• Removing Ember.js best practices (obtainable via MCP tools)
• Removing detailed architecture info (can be found via codebase exploration)
• Keeping only: MCP server directive, configuration, and codebase-specific development guidance

Added .vscode/settings.json with configuration for:

• Local MCP server using ${workspaceFolder}/index.js
• Copilot instructions file reference
• Uses VSCode's servers key (not mcpServers like Claude)

The configuration uses workspace-relative paths so it works for anyone who clones the repo.
