Container

Swamp execution driver that routes every model method through Apple's container CLI (macOS 15+). Each execution runs in its own Virtualization-framework microVM — a stronger isolation boundary than Docker's shared-kernel containers, and the right default for agentic or LLM-driven workloads. Two modes, matching swamp's built-in docker driver: bundle mode (self-contained JS bundle in a Deno-capable image) and command mode (sh -c "<run>" inside the image). Opt in via defaultDriver: "@bixu/container" in .swamp.yaml, or per workflow/job/step/model. Requires /usr/local/bin/container (Apple's container CLI 1.0+).
