chore(config): Add local MCP server configuration

Add .mcp.json to define project-specific MCP servers:
- ardour: Local ardour-mcp server for DAW control
- midi-gen: MIDI generation server for music composition

This enables AI-assisted development workflows when working on the
Ardour codebase, with automatic MCP server loading for testing and
integration work.
