Cmux Shared Behavior

Prevents the classic bug where you fix something in the UI but forget the keyboard shortcut still runs the old broken code. This enforces a single mutation path when behavior surfaces through multiple entrypoints like command palette, context menus, CLI commands, settings, and debug tools. Also covers the optimistic update pattern: one mutation path, track pending state with request IDs, reconcile against the authoritative result, and roll back explicitly on failure. The missed-bug coverage rule is smart: if tests didn't catch something, you add behavior-level tests around the exact repro before calling it done. Basically architectural discipline for cmux to avoid duplicated logic across surfaces.
