feat: add embedded MCP server and Makefile

Browse Source 
Add an MCP (Model Context Protocol) server that starts on 127.0.0.1:9427
at app launch, sharing connection pools with the Tauri IPC layer. This
lets Claude (or any MCP client) query PostgreSQL through Tusk's existing
connections.

MCP tools: list_connections, execute_query, list_schemas, list_tables,
describe_table.

Also add a Makefile with targets for dev, build (cross-platform),
install/uninstall, lint, and formatting.
