What is the best setup for AI-assisted coding, including: IDE (Cursor, VSCode, Windsurf, Zed, etc). AI assistant (LLM) like Claude, Gemini 2.5 Pro, OpenAI, DeepSeek. MCP, rulesets, extensions, tools, workflow, and anything else?

And what kind of project are you building/maintaining with it (framework, language, deployment infra, aprox # of users)?
