feat(docker): resilient agent image pre-pull with retry + fallback - #5

Conversation
Docker-mode tasks relied on `docker run`'s implicit pull, so a transient Docker Hub registry timeout hard-failed the task with a cryptic daemon error. Add a pre-pull step in front of `docker run`: - fast path: a cached image spawns synchronously (cached per session) - missing image: `docker pull` with 3 retries + backoff, streaming progress - fall back to any locally cached copy before giving up - friendly error + clean exit instead of a raw daemon dump - cancellation-safe on kill / renderer reattach mid-pull Project images (forge-project:*) and non-Docker tasks are unchanged.
