ESF (Engineering Software Factory) preview

ESF is a self-hosted platform that runs coding agents in isolated microVM sandboxes, verifies their changes against deterministic gates, and preserves the resulting patch and execution evidence, with Temporal coordinating the workflow. It's an independent fork of the Machinist project, keeping its CLI, local control plane, and web UI while adding factory-style orchestration for named agent harnesses and repository policies. It targets engineering teams that want isolation and verifiable evidence, not just an agent's own claim of success.
