sandbox@4.9.0

Minor Changes

• Add sandbox extend to increase a running session's timeout without changing future session defaults, and clarify sandbox config timeout help. (#389)

• sandbox drives get-or-create --max-size now accepts sizes with units (200GiB, 2TiB) as well as raw bytes, and rejects input it cannot parse instead of truncating it, so 2TiB is no longer read as 2 bytes. When --max-size is omitted, the printed size says where it came from: max size: 1 TiB (set with --max-size at creation, fixed afterwards). (#342)
