osobhandClaude Opus 5.5 8df5b209a7 clawhdf5-remote, h5rs: never allocate a length the server only claims ...

h5rs check URL read the whole file with one read_at(0, len), len being
whatever Content-Range said. BlockCache listed every block index of the
span and preallocated len bytes: a server claiming 2^62 bytes for a 10 KB
file made h5rs abort (memory allocation of 35184372088832 bytes failed).

- BlockCache: a read spanning more than the budget (or eight max_requests)
  is fetched piece by piece and not kept, its output growing only as
  data arrives; read_ranges falls back to that per range; prefetch is
  clamped to the budget.
- New clawhdf5_remote::download(storage, max_bytes): refuses a claimed
  length above the limit (RemoteError::TooLarge) before any request, then
  reads in 64 MiB steps. New RemoteError::Backend for read errors.
- h5rs check downloads through it, with --max-download N (default 1 GiB).
