• FEATURE: vmestimator: add churn_interval stream config option. When set, vmestimator emits cardinality_churn_ratio metrics measuring how quickly the series set changes within the measurement window. The ratio is computed as (2*|A∪B| - |A| - |B|) / |A∪B| where A is the retained HLL snapshot and B is the current sketch, resulting in a value in [0, 1] where 0 means a stable series set and 1 means complete churn. See churn-calculation and #24.
• FEATURE: vmestimator: simplify overflow handling in the deduplicator. Expose vmestimator_deduplication_passed_total, vmestimator_deduplication_dropped_total, vmestimator_deduplication_bloom_filter_size, and vmestimator_deduplication_bloom_filter_max_size metrics for monitoring deduplication effectiveness. See #48.
