v4.4.3

Renderer-only release — no schema change, no API change.

Fixed

• Downloading a server-only folder no longer makes it vanish, then come back as local-only.
  After the files landed on disk, download asked the store to drop the folder row so a refresh
  could pick it up as a real local folder. That store action now prefix-prunes every file under
  the folder and their cached server rows — added so a delete would not resurrect as a cloud
  ghost — and download no longer ends with a full reload. The incremental "these files are
  downloaded" updates then matched nothing, the folder disappeared from the parent, and the
  file-pane Refresh (disk only, no server refetch) rematerialized the files without any server
  metadata, so they showed as local-only. A later full vault load was the only thing that put
  the badges right. Download now leaves the folder in the store and clears its cloud status in
  the same update as the files, including nested cloud directories that the download just gave
  local content. Reported from doris: Burn Wire Release, 33 files.
