Subject: [PATCH] fix(sandbox): add { once: true } to Docker abort signal
 listener

Align the Docker sandbox abort listener with the rest of the codebase
(15+ other abort listeners all use { once: true }). Without this, the
listener can accumulate in long-running sessions with many tool calls,
causing memory pressure.
