refactor: move platform workspaces from packages/ to apps/ and decouple site deps

Platform packages are internal deployment wrappers, not publishable
artifacts. Moving them out of packages/ keeps the publish workflow's
globs untouched and matches the repo convention (apps/* = internal,
packages/* = published).

Also removes @node-core/platform-vercel and @node-core/platform-cloudflare
from apps/site's dependencies. They're now declared as optional peer
dependencies so:

- A standalone install (no DEPLOY_TARGET) pulls in zero platform deps.
- Vercel's installCommand scopes install to @node-core/website and
  @node-core/platform-vercel (skipping Cloudflare/OpenNext deps).
- The Cloudflare deploy workflow scopes install to @node-core/website
  and @node-core/platform-cloudflare (skipping @vercel/* deps).
