* improvement(files): cache stream binding meta, tighten file cache-control, prune dead persist path - Cache the agent-stream ProseMirror↔Yjs binding metadata per session and reuse it across streamed frames instead of rebuilding it (O(doc)) every frame; matches how y-tiptap's own binding maintains the mapping in place. Safe because the shadow doc only ever sees the agent's own reconciles. - Default createFileResponse to a private, no-cache policy so auth-gated bytes are never stored in a shared cache; genuinely-public serve routes opt into public caching explicitly. - Serve content-addressed (key=) embedded images with an immutable private cache to avoid re-downloading them on every doc re-open; fileId= embeds and public shares keep revalidating (the underlying key can change / a share can be revoked). - Drop the dead conflict.version field from the collab-doc persist result and remove the wasted getWorkspaceFile re-read on the conflict path (the relay treats missing and conflict identically and never read version). - Decorate-sort the files/folders lists (compute each sort key once) and index the move-menu subtree build (O(N) vs O(N^2)); ordering is preserved exactly. * fix(files): serve inline images with no-cache so deletion/authorization is enforced per request Embedded images are authenticated content whose backing file can be deleted or have its access revoked at any time. Both key= and fileId= embeds serve private, no-cache, must-revalidate, so every request re-runs the server-side deletion/authorization check instead of serving a possibly-stale image from cache.
