Add MCP support

In particular, context7 is a very interesting MCP server that pulls in relevant docs.

We need this thanks @wwwillchen

I feel that mcp's for supabase, vercel and GitHub would make sense to build first to give dyad full control of the dev cycle. As it is I need to paste logs from edge functions that dyad could have read. Yes, it's hackable with env vars and curl instructions, but that won't lead to massive adoption 😇
