feat: add Set B profiles and low-latency native haptics

Add schema-6 profiles, atomic catalog migration, shortcuts, Shift, configurable Turbo/Burst, macro recording and playback. Promote qualified 300 MHz native DualSense transport to AIO/XInput defaults with bounded bus transactions, credit batching and generation-safe persistent rumble.
