Manage matter workspaces — new, list, switch, close, or detach (practice- level). Creates, lists, switches, closes, and detaches the active matter so context from one client engagement never leaks into another. Use when a multi-client practitioner says "new matter", "switch matter", "list my matters", "close this matter", or needs to manage which matter is active.
