📄 Description

Improves native Triton input handling, bringing it more in line with SDL's protocol definitions and timing behavior, with particular attention to source timestamps, motion data, touch state, and native timestamped reports.

The goal is to preserve more of the controller's native timing and contact state so downstream USB reports expose consistent IMU and touch behavior.

Changes:

Adds support for the native Triton report 0x47 alongside the existing input report paths.
Carries source IMU timing into the decoded controller input state.
Propagates sensor timing into host-facing motion reports where the target protocol supports it.
Adds stateful touch-contact packing so touch IDs and release transitions remain stable across reports.
Preserves distinct left/right touch sources when a single contact moves between pads.
Updates the Steam HID descriptor to advertise the additional native input report.
Keeps the common decoded-input path synchronized across the Steam, SDL/SInput, HID-gyro, and DualSense-facing consumers.
Retains the existing fixed-rate USB streaming behavior for personalities that consume the latest decoded state.
