`up` hangs indefinitely when the container start event is missed (warm daemon + cached image)

[Omotola]

What happened
On a warm Docker daemon with an already-built/cached image,  devcontainer up occasionally hangs forever. The container is created and running, but the CLI never proceeds to the lifecycle hooks.

Root cause
In  spawnDevContainer ,  startEventSeen  spawns docker events --filter event=start and then docker run follows almost immediately. With a cached image the container starts before the events listener has finished subscribing, so the start event is missed and awaited indefinitely.

Impact
 up hangs with no timeout; lifecycle hooks ( onCreate / postCreate / postStart ) never run.

Environment

•  @devcontainers/cli : 0.60.0
• Docker Engine: 29.6.1 (API 1.55), backend linux/amd64
• Node.js: v24.12.0 (from your Output pane), host Windows 10.0.26100

• Repro: warm daemon, image already cached, then  devcontainer up

Hi @Omotola

Would you kindly use a newer version of the cli(current latest version 0.88.0) and let me know if you are facing the same problem? If you are still facing the same, kindly provide the dev container configuration you are using which is causing this issue.
