Under the hood
Auto-mode environment setup onboarding now waits for repeated denials before offering again
Each time the auto-mode environment setup prompt is denied, a denials counter on autoModeEnvSetup increments, up to a cap of 5, and the onboarding is only offered again once that many denials have accrued, alongside a startup-count threshold, no existing environment config, and not having been previously dismissed. Choosing "later" or "dismiss" now records dismissedAt/dismissed and emits a tengu_auto_mode_env_onboarding_later event.
