Class-level UIKeyInput conformance without UITextInputTraits means iOS
falls back to default traits — autocorrect on, predictive on, smart
quotes/dashes on. The suggestion engine was swallowing most keystrokes
before insertText() could forward them (the "1 in 6 chars" symptom).
Declaring all the traits as @objc stored properties with permissive
(autocorrect=.no, etc.) values turns every suggestion layer off so each
key tap produces exactly one insertText() and hits the remote.
