Subject: [PATCH] fix(ai): classify product-noun prompts as Design intent
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

classify_intent matched only creation verbs, so a noun-phrase request like
"Luxury webapp for managing barbershop clients" fell through to the weak chat
loop instead of the orchestrator. Add product/app nouns (webapp/web app/website/
app for/mobile app/admin panel/saas + 网站/网页/小程序/后台) to DESIGN_KEYWORDS.
