idempotentGlobalActions

The subset of global_action action strings that are safe to retry — state-toggles or navigations whose final state is the same regardless of how many times the call runs. Dispatchers consume this to attach idempotentHint = true at call-site rather than splitting global_action into one tool per action.

Excluded: back (each call navigates one step further), recents (a toggle — a second call closes it), power_dialog (user-facing modal) and screenshot (a capture action, not nav/state).
