LivoxGen1: Port to coros

No longer uses CPS. We also found and documented a potential bug in
the way we deal with disablePcloudData during detachDeviceReq.

+# Adapter Awaiters
+
+This directory contains coroutine/awaitable adapters that wrap callback-driven
+or event-driven APIs.
+
+## Placement rules
+
+- Put wrappers for external APIs in provider-specific subdirectories.
+  - Examples: `boostAsio/`, `opencl/`, `liburing/`.
+- Put wrappers for SMO/internal APIs in `smo/`.
+- Do not place adapter awaiters in feature folders like
+  `stimBuffApis/*` or `smocore/*` unless they are strictly private to one
+  translation unit.
+
+## Tree layout
+
+```text
+include/adapters/
+  README.md
+  boostAsio/
+    <boost asio adapter awaiters>
+  opencl/
+    <OpenCL adapter awaiters>
+  smo/
+    cpsCallbackAReq.h
+    livoxProto1CpsAwaiters.h
+    <other SMO/internal callback adapters>
+```
+
+## Design guidelines
+
+- Name adapter awaiter wrapper functions `get<fnName>AReqAwaiter()`, where
+  `<fnName>` is the wrapped CPS/API request symbol with its library prefix
+  removed and each `_`-delimited segment Pascal-cased (e.g.
+  `livoxProto1_getOrCreateDeviceReq` → `getGetOrCreateDeviceReqAReqAwaiter()`).
+- Keep adapters small and single-purpose; but unify where possible to reduce
+  code duplication.
+- Make result types explicit for multi-argument callbacks.
+- Resume coroutines on a caller-specified executor/io_service.
+- Avoid embedding business logic in adapters.
