perf(web): edge-cache public pages; drop static-split build

Take the standard single-Worker path instead of the static-split: add
Cache-Control (s-maxage + stale-while-revalidate) to the public marketing/docs
routes so Cloudflare's CDN serves repeat hits to the same URL without invoking
the Worker. Scoped to public paths only — /api, /dashboard, /sign-in, /sign-up,
/scratchpad stay dynamic/no-store.

Removes the interim static-split artifacts (scripts/build-web-static.mjs,
wrangler.web.jsonc, build:web/deploy:web) — the split fought OpenNext's
single-deployment model and the apex re-routing was too risky for the benefit.
