e49e5895c1 feat(mqtt): add session persistence, QoS 2 state machine, and retained store (E2+E3) 
Add MqttSessionStore with save/load/delete/list operations, flapper
detection (backoff on rapid reconnects), and TimeProvider-based testing.
Add MqttRetainedStore for per-topic retained messages with MQTT wildcard
matching (+/# filters). Add MqttQos2StateMachine tracking the full
PUBREC/PUBREL/PUBCOMP flow with duplicate rejection and timeout detection.

19 new tests: 9 session persistence, 10 QoS/retained message tests.

b6c373c5e4 feat(mqtt): add MqttBinaryDecoder with CONNECT/PUBLISH/SUBSCRIBE parsing and 27 tests 
Port binary MQTT 3.1.1 packet body decoding from Go mqtt.go (~lines 700–1500, 2200).
MqttBinaryDecoder parses CONNECT (protocol name, connect flags, keepalive, client ID,
will topic/message, username, password), PUBLISH (topic, packet ID for QoS>0, DUP/
RETAIN flags, application payload), and SUBSCRIBE (packet ID, topic-filter + QoS list).
Adds TranslateFilterToNatsSubject for simple MQTT wildcard conversion (+ → *, # → >,
/ → .). All 27 tests in MqttBinaryParserTests pass.
