Coves frontend - a photon fork

feat(post): optimistically render freshly created posts master

The create flow now assembles a PostView from the form data and hands it to the post page through a one-shot stash, so the redirect renders the post immediately (~250ms incl. the create call) instead of racing the AppView indexer — no getPost round-trip, and the comments fetch is skipped straight to the empty state (asking before the post is indexed 404'd into 'Failed to load comments'). The ?uri= retry poll remains as the fallback for hard reloads. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
