Service Detection

Type	Detection	Default Port
Vite	vite.config.*	5173
Next.js	next.config.*	3000
Nuxt	nuxt.config.*	3000
CRA	react-scripts in package.json	3000
Express/Node	server/backend/api directory + package.json	3000
FastAPI/Flask	requirements.txt / pyproject.toml	8000
Go	go.mod / main.go	8080

Port Detection Priority: User specified > .env > config file > scripts args > default port
