Added

• Transfer Pak UI — New TransferPakConfigView allows mounting GB/GBC ROM files into Mupen64Plus N64 controller-port Transfer Pak slots. Access via long-press context menu on any N64 game or via the Transfer Pak tile in the pause menu (only appears when the running core supports Transfer Pak). Feature-flagged off by default; enable in Settings → Advanced → Feature Flags → "mupenTransferPak"
• Transfer Pak Feature Flag — Added mupenTransferPak to the PVFeature enum and features.json, defaulting to disabled. Enables the Transfer Pak configuration UI once the feature is sufficiently tested
• Known Transfer Pak Games List — TransferPakCompatibleGames enumerates N64 titles that use the Transfer Pak accessory (Pokémon Stadium, Mario Tennis, Mario Golf, Perfect Dark, and others) so the app can auto-prompt users to configure the feature
• Persistent Slot Configuration — TransferPakStore persists the selected GB/GBC ROM path per N64 game and per controller port in UserDefaults, so settings survive app restarts
• Transfer Pak Auto-Apply at Launch — Persisted Transfer Pak slots are applied automatically via PVEmulatorViewController when an N64 game starts and the core conforms to TransferPakSupport
