feat: MCP config should default to project-level, not global

[notdp]

Problem

When running npx -y grab@latest init and selecting MCP connection for agents (e.g., Claude Code, Codex, Droid), the MCP server configuration is written to the global config files:

• Droid → ~/.factory/mcp.json
• Claude Code → ~/.claude.json
• Codex → ~/.codex/config.toml

This means the react-grab-mcp server is enabled for all projects, not just the one where React Grab was installed.

Expected Behavior

The MCP config should be written to project-level config files by default. For example:

• Droid → .factory/mcp.json (in project root)
• Claude Code → .claude/settings.json or .mcp.json (in project root)

This keeps the MCP server scoped to the project that actually uses React Grab.

Suggestion

Either:

1. Default to project-level MCP config (preferred), or
2. Add a prompt during init asking users to choose between project and global scope for MCP configuration

Environment

• React Grab: 0.1.19
• OS: macOS
• Agents: Claude Code, Codex, Droid
