Pull request overview
This PR strengthens DualSense (DS5) adaptive trigger feedback handling in the Sunshine DS5 sidecar by adding stateful, per-trigger change detection and lifecycle reset behavior, while keeping the existing 26-byte adaptive trigger payload shape and the 0x5503 output path unchanged.
Changes:
- Advertises
AdaptiveTriggerscapability in Hello/Attach replies and adds protocol self-test coverage for capability + encoding. - Introduces
AdaptiveTriggerStateto track left/right effects independently, suppress duplicates, and emit only when actual changes occur. - Serializes output emission vs. disposal and sends a trigger reset on session disposal to avoid leaving residual trigger resistance.

改了啥呀
为啥要改
HIDMaestro 的左右扳机字段不保证总是同时变化。旧实现要求两侧字段同时存在，并且每次固定发送
0x0C，容易漏掉单侧变化、重复发送相同状态，还可能在会话结束后留下旧效果。这次保持现有 26 字节 Sidecar payload 和 Sunshine
0x5503出口不变，只补强状态管理和生命周期，不折腾已经能工作的协议啦。验证
