Suspend in progress


`type`	`https://docs.frem.sh/reference/api/errors/suspend-in-progress`
HTTP status	`409` Conflict

What it means

A suspend is already running on this bench, so a second request would change nothing.

Example detail messages returned with this error:

Wait, then read state from GET /benches. A suspend normally finishes within a minute. If the bench ends up in error, see bench-in-error.

All fremforge API errors are RFC 9457 problem+json:

{
  "type": "https://docs.frem.sh/reference/api/errors/suspend-in-progress",
  "title": "Conflict",
  "status": 409,
  "detail": "..."
}

Branch on type, not on title or detail - those are human-readable and may be reworded.
