Crush v0.100.0 adds named background subagents and a Sysadmin mode
Released Nov 5, Charm's terminal agent can now dispatch named background subagents, message them mid-run, stop them, or move them to another model, and calls running past 60 seconds auto-background. It also adds a Sysadmin mode that can run any command, user-defined permissions safe/block/unblock lists, and GPG/SSH prompts inside the TUI.
