feat(core,fuse): restore the whole trashed tree, and bump the SDK to 0.6.5

The trash is a flat list of uids, but a delete has a shape: a folder, and
often items inside it that were trashed separately beforehand. Restoring
one of those in isolation is not what it means — a folder came back
without the contents deleted with it, and a file came back inside a
folder that is still trashed, which is to say nowhere the user can see.

- Schema 29: `trash.parent_uid`, filled by the trash refresh from the
  node's parent, plus an index for the walk.
- `expand_restore` takes the connected piece of the trashed tree around
  what was asked for (every trashed descendant, every trashed ancestor)
  and orders it into waves, shallowest first: the server cannot put a
  node back under a parent that is still trashed. A uid the listing does
  not know about is restored on its own, because the listing is
  materialised in chunks and can be stale.
- `Core::restore` restores wave by wave, still streaming per-node
  outcomes, so one node the server refuses leaves the rest restored.

The SDK bump brings the 6cbf2f44 port: permanent API errors are no
longer retried on block transfers, expired block URLs are re-minted on
the whole-file and public-link download paths, and a server-supplied
Retry-After is capped at 120 s.
