Hook results say when the hook was backgrounded

A hook left running in the background is now flagged as backgrounded instead of looking finished.

What

A hook that is detected as async and allowed to keep running now reports backgrounded: true alongside its stdout, stderr and exit status, so a hook left running is distinguishable from one that finished.

Details
  • When sync execution is forced, the hook is waited on to completion instead and logs that it is doing so.
Evidence

Hooks: Detected async hook but forceSyncExecution is true, waiting for completion

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
