Janis	676e4110c0	feat(core): publish GameOver event to Redis Streams (#64 ) Add GameOver to EventType enum and GameOverPayload DTO. GameRedisPublisher publishes to {prefix}:game-over stream (MAXLEN ~1000) on game completion. NativeReflectionConfig updated for core module.

Janis	0ad2e10999	feat(bot-platform): migrate BotRegistry to Redis Streams consumer group (#63 ) Replace pub/sub subscribe with XREADGROUP on bot game-start stream. Remove dual-write from EventPublisher.publishGameStart. Consumer group: bot-platform-consumer, XACK after forwarding. Poll loop uses emitter identity to prevent thread leak on re-registration. Group created with '$' offset — no historical replay on first connect. Closes NCS-101 https://knockoutwhist.youtrack.cloud/issue/NCS-101 Reviewed-on: #63	2026-06-09 21:48:21 +02:00
