* fix: marshal provider events onto the source thread ModuleProxy's event listener emitted eventResponse directly on whatever thread the module fired the event from (its worker/FFI thread). QtRemoteObjects then serialized and sent the event from that foreign thread, racing the source socket against a method reply being sent from the source thread, which silently dropped the reply. This is why a method that emits an event mid-call never returns to the caller (e.g. delivery_module start(), which emits connectionStateChanged as the node connects) while a method that emits nothing (createNode) returns fine. Marshal the emission onto the ModuleProxy's own thread via a queued invocation so events and method replies are serialized on the single thread QtRemoteObjects expects to own the source.

AutoConnection invokes synchronously when already on the source thread and only queues cross-thread emissions (the actual fix); passing 'this' as context cancels a queued call if the object is destroyed first. --------- Co-authored-by: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
