• Controller Slot Preferences — PVControllerManager now supports three slot-assignment modes per controller: .auto (unchanged first-available-slot behaviour), .preferred(n) (use slot n if free, else auto-assign), and .always(n) (always claim slot n, bumping the current occupant). Preferences persist across app launches and are applied on every connect/reconnect. A public reapplyPreferences() method re-applies all stored preferences after tvOS focus/wake events. Conflicts (two controllers both set to .always(n)) are handled gracefully — last-connected wins, warning logged. API: slotMode(for:), setSlotMode(_:for:), clearSlotMode(for:), preferredPlayer(for:), setPreferredPlayer(_:for:), reapplyPreferences().
