* Marshal inter-module calls to the owner thread Logos inter-module calls go over Qt Remote Objects, whose replicas only work on the thread that created them (the module's main/event-loop thread). A module that makes calls from a worker thread — e.g. an embedded HTTP server serving /metrics — would otherwise hang on replica acquisition. Make LogosAPIClient transparently marshal to its owner thread when called off-thread (guarded so same-thread calls run directly with no overhead): - LogosAPI::getClient creates the client/consumer/replicas on the owner thread - LogosAPIClient::invokeRemoteMethod / requestObject / onEvent run there too New header logos_thread_marshal.h (runOnOwnerThread). No new data members — ABI-safe for statically-linked plugins.

The call must execute on the owner (main/event-loop) thread, not the worker thread. Fails without the marshaling change (the call runs on the worker thread — 0x..d80d0 vs owner 0x..c53e0, "executed on the worker thread instead of the owner thread"); passes with it (511/511).

The HTTP handler calls sensor_module.readTemperature() from the server's worker thread — which only works because the SDK marshals the cross-module call onto the module's owner thread. The module stays pure C++. Wired into doctests/run.sh and the doctests CI workflow. Validated locally (23/23 steps pass): `curl` returns `temperature 42`.
