Declare bareMobileTerminalAliases as private nonisolated static let.

TerminalController is @MainActor-isolated, and this immutable alias table does not access actor state. Match focusIntentV1Commands and focusIntentV2Methods.

In `@Sources/TerminalController.swift` around lines 14401 - 14404, Update the
bareMobileTerminalAliases declaration in TerminalController to include
nonisolated alongside private static let, matching the isolation annotations
used by focusIntentV1Commands and focusIntentV2Methods.
