1.0.83-2

Added

• Custom agents can list several models in model, tried in order until one is available to you, and model-policy: required keeps model changes on that list
• Adding support for claude-fable-5.1

Improved

• Linux sandboxes now restrict network egress to the configured proxy; proxy mode requires slirp4netns, util-linux 2.35+, iptables, and /dev/net/tun access
