Google AI subscription updates from I/O 2026

Google AI 订阅服务全新内容，源自 I/O 2026 大会

Google announced a $100 AI Ultra subscription at I/O 2026 and added new features and benefits for existing Google AI Plus, Pro, and Ultra subscribers.

Why it matters: HKR-H comes from the $100 Ultra hook; HKR-K from the disclosed tiering and price; HKR-R from cost and vendor-selection pressure. Capability limits are not disclosed, so this stays at the low end of featured.
