fix(Windows): queue VHF input reports

[ReenigneArcher]

Description

Add a bounded VHF input-report queue for the UMDF backend so reports are only submitted when VHF signals readiness. Continuous state updates now coalesce to the latest value while discrete button, D-pad, trigger-threshold, report-ID, and touch-contact transitions stay ordered, and Switch protocol replies are prioritized to keep the handshake responsive. Also document the buffering policy and add unit coverage for queue behavior across supported Windows gamepad profiles.
