• result_handler: Guard _handle_success when coverage gate blocks node (#722)

  Fixed an ordering bug in SessionResultHandler.process() where the coverage regression gate would block a coder node and cascade-block its dependents, but _handle_success() would then unconditionally mark the same node as completed — leaving dependents permanently orphan-blocked with no path to unblock. This caused irrecoverable stalls in runs where a coder introduced a coverage regression.
