- Fix trackball completely dead: remove gpio_reset_pin() calls that prevented GPIO interrupts from registering on ESP32-S3 - Add trackball left/right tab cycling when screen doesn't consume event - Add NameInputScreen: Ratspeak-branded first-boot name input - Add display name to all announces as MessagePack app_data - Add TEXT_INPUT setting type; expose Display Name in Settings - HomeScreen Enter key sends announce with toast notification - Bump version to 1.2.2
