Worker: run_worker_first so dynamic / handler actually runs

Cloudflare Workers Static Assets serves exact-match files directly
from the edge without invoking the Worker by default. That meant my
new /-intercepting handleIndex was never reached for /index.html —
CF kept returning the cached static index.html.

run_worker_first = true makes every request go through the Worker
first; static assets are still served via env.ASSETS.fetch when the
Worker dispatches to it.

Also adds a console.error in the / fallback path so future silent
failures surface in wrangler tail.
