1.1.2

• Report Backpressure Mechanism — HotKeyReporter.flush() changed to enqueue via LinkedBlockingQueue.offer(timeout), no longer direct publish. When queue is full, after 100ms timeout it discards with WARN, backpressure naturally flows to Caffeine 30s eviction for rate limiting.
• Dedicated Consumer Thread Pool — HotKeyReporter starts N daemon consumer threads (max(1, shardCount/2), configurable consumerCount) consuming from bounded queue and publishing to RabbitMQ. Each consumer checks 5s expiration when dequeuing, silently discarding expired entries.
• New Configuration Properties — HotKeyProperties added queueCapacity (default 10000), queueOfferTimeoutMs (default 100), consumerCount (default 0 = auto), prefix hotkey.local.*.
• Actuator Queue Metrics — HotKeyEndpoint added 4 monitoring fields: reportQueueDepth, reportQueueCapacity, reportExpiredCount, reportQueueFullCount, injected via ObjectProvider<HotKeyReporter> into HotKeyActuatorAutoConfiguration.
• Reporter Lifecycle Management — HotKeyReportAutoConfiguration uses initMethod = "start" and destroyMethod = "stop" to manage HotKeyReporter dispatcher threads.
• Negative Shard Routing Fix — HotKeyReporter shard routing changed from Math.abs(key.hashCode()) % shardCount to Math.floorMod(key.hashCode(), shardCount). Eliminates Integer.MIN_VALUE edge case where Math.abs(Integer.MIN_VALUE) returns negative causing array index out of bounds.
• Checked Exception Propagation Fix — HotKeyAspect replaced throw new RuntimeException(e) with Lombok-free sneakyThrow(e), preserving original checked exception types through Supplier/Runnable lambdas in handleRead and handleWrite, so callers don't need to catch RuntimeException wrapper.
• Fixed known bugs
