feat: notebooks with coding agents integration

[emrberk]

• Pull this branch, then yarn && yarn start and see web console on localhost:9999 as before.
• Clone https://github.com/questdb/mcp-bridge and yarn && yarn build. We will use the script ...clone path.../mcp-bridge/dist/index.js in the next step.
• Configure the MCP:
  • In Codex, there is a UI to set up the MCP (field values the same as below), or you can run codex mcp add questdb --env CONSOLE_ORIGIN=http://localhost:9999/ -- ...clone path.../mcp-bridge/dist/index.js
  • For using with Claude, find the Claude config file (~/.claude.json on Mac). Then add this to the config:

"mcpServers": {
    "questdb": {
      "type": "stdio",
      "command": "...clone path.../mcp-bridge/dist/index.js",
      "args": [],
      "env": {
        "CONSOLE_ORIGIN": "http://localhost:9999/"
      }
    }
  },

• Start Claude, you should see questdb (connected) in the list when you type command /mcp.
• Ask it to pair with web console and then follow Claude instructions. You can also directly say "create ... dashboard in web console" and it will guide you.
