-type command_options() ::
          #{deadline_ms => 1..600000,
            max_stdout => 0..1048576,
            max_stderr => 0..65536,
            stdin => binary(),
            identity => observed | same_connection}.
```

Command options: deadline_ms defaults to 2500, max_stdout to 1 MiB, max_stderr to 64 KiB, stdin to an empty binary and identity to observed. The deadline includes admission, preflight and execution. stdin is limited to 256 KiB; stdin plus the rendered argument reservation must also fit 256 KiB. Each endpoint admits at most 64 operations and 256 KiB of command payload; exhaustion returns busy. same_connection is recognized but unsupported.
