fix(index-builder): run wrangler from /app/web to pick up functions/ bundle

Browse source 
_worker.js static file approach fails — Cloudflare rejects it when uploaded
as a static asset. Instead, copy web/functions/ into the image and set
wrangler CWD to /app/web/ so it discovers functions/ and uploads the Pages
Functions bundle correctly on every deploy cycle.
