chore(cloudflare): drop cd-prefixed scripts and ignore wrangler state dir

Replace `cd ../site && ...` in the three cloudflare scripts with
`pnpm --filter=@node-core/website exec ...` so pnpm sets cwd transparently
(per Dario's review feedback). Ignore apps/cloudflare/.wrangler, which is
where wrangler v4 writes its state dir relative to the config file.
