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.
