fix(demo): default WRANGLER_CMD to npx + silence expected R2 not-found probes

The publish scripts shelled bare `wrangler` (ENOENT without a global install)
and the existence probes (registry.json / per-tool meta.json) printed wrangler's
'key does not exist' on a fresh bucket. Default to `npx wrangler@4` and capture
stderr on probes.
