Kill one subprocess
Sends a signal to the process group of spid inside the
running instance. Without the signal parameter the group
gets SIGKILL. Termination is observable, not returned: the
exit event lands in the event log and
GET /operations/{operationId}/subprocesses/{spid} reports
the terminal state (signal set, exit_code -1 when killed).
Killing spid=1 (the main process) effectively ends the
operation, like letting the command fail.
Authorizations

Authorization: Bearer <iam-token>. Must be combined with the
Project header (see IAMProjectHeader).
This is the recommended authentication scheme for new clients.
Nebius project ID associated with the IAM token. Required together
with IAMBearerAuth. Identifies the project context the request is
scoped to.
