Renew voice sessions while the host app stays foreground, auto-start flow from the keyboard with a Start action, and prevent leading audio loss via pre-roll buffering and faster signal polling.
XcodeGen merged Localizable.strings into the main app only, so the keyboard
extension had no .lproj files and NSLocalizedString returned raw keys. Use a
dedicated Keyboard.strings table and explicit buildPhase: resources entries.
