This is used to recover stuck steps when a worker dies mid-task.
The issue is moved to "open" status and the assignee is cleared,
allowing another worker to claim and complete it.

Examples:
  gt release gt-abc           # Release single issue
  gt release gt-abc gt-def    # Release multiple issues
  gt release gt-abc -r "worker died"  # Release with reason

This implements nondeterministic idempotence - work can be safely
retried by releasing and reclaiming stuck steps.`,
