Converts all MoQRelayTest TEST_F cases to TEST_P and instantiates them under AllModes/MoQRelayTest with named variants (SingleThread, MultiThread). MoqxTrackFilterTest overrides relayMode() to always return SingleThread so it stays as TEST_F without GetParam() UB. MoqxRelayTestModes.cpp is added only to moqx_relay_test (not the shared fixture library) to avoid a GTest warning in moqx_track_filter_test.
Adds a use_relay_thread boolean config option (default: true) that controls whether relay state is isolated on a dedicated executor thread. Disabling it is intended for baseline performance comparison only. Also removes the hard error that rejected threads > 1, replacing it with a targeted check: threads > 1 requires use_relay_thread=true. This unlocks the config validation only — threads > 1 with use_relay_thread=true will race on shared relay state until the following commit wires up the dedicated relay executor.
Add RelayMode::MultiThread to the MoQRelayTest parameterized suite so the relay is exercised across an executor boundary, alongside the existing SingleThread mode. Fixture (MoqxRelayTestFixture.h/.cpp, MoqxRelayTestModes.cpp): - New RelayMode::MultiThread enum value, instantiated in the AllModes suite. - SetUp() starts a ScopedEventBaseThread, wires the relay onto it via setRelayExec, and wraps it in PublisherCrossExecFilter / SubscriberCrossExecFilter. TearDown() drains pending relay-exec tasks and tears down in order to avoid use-after-free on NamespaceTree. - TestMoQExecutor::drive() does a loopOnce(), then in MT mode round-trips through the relay EVB twice to flush task->relay and relay-created tasks. - Add driveIfMultiThread(), make verifyOnRelayExec() hop to the relay EVB, and add driveUntil(pred) to advance async cascades deterministically instead of using a fixed drive count (capped at one iter in ST mode). Tests (DataPlane, NGR, Peer, Publish, SubNs, Subscribe): - Insert driveIfMultiThread() where work crosses executors. - Replace fixed-drive-then-read with driveUntil() plus std::atomic flags. - DuplicateSubgroupCancelledWhenNoActiveConsumers splits ST/MT expectations: in MT the CrossExecFilter defers the CANCELLED error to the next op, so it probes via endOfSubgroup(). - Add reset() calls to simulate the publisher/QUIC resetting open streams.
