Method spawn

apps/hash-graph/src/subcommand/mod.rs:63–80

Spawns a named server task. If the future completes while `shutdown` has not been requested, this is treated as an unexpected exit and `abort` is cancelled to trigger shutdown of all remaining components. This also fires on panics via the [`ShutdownGuard`] drop implementation.
