Skybridge build fails when no widget is registered

Context

Hey there :) I wanted to use Skybridge as a framework for a regular MCP server (no ChatGPT/MCP App).

I registered a tool in the server/ folder and have no web/ folder, and tried to build the project but got the following error:

✘ [ERROR] Could not resolve "/Users/neil/Build/folder/apps/mcp-server/web/vite.config.ts"

failed to load config from /Users/neil/Build/folder/apps/mcp-server/web/vite.config.ts
error during build:
Error: Build failed with 1 error:

Expected behaviour

I should be able to use Skybridge only for the server part without having to add a placeholder vite.config and widget in the web/ folder.
