…etry Implements the CCKR (Chao-Cohen-Kaplan-Reservoir) adaptive log sampler as implementations of the existing LoggingSampler and LogBuffer seams, so no changes to the logging pipeline are required: - Cckr<TCallsite,TPayload>: bottom-(K+1) weighted reservoir with EXP ranks, cross-period inverse-frequency feedback, Chao1 unseen-weight, bounded novelty preserve, and Horvitz-Thompson sampling weights (faithful port of the reference algorithm). - CckrLoggingSampler (LoggingSampler): the admit/drop decision. CckrLogBuffer (LogBuffer): holds admitted records per category and emits the kept records carrying the sampling.count weight at each flush, reusing SerializedLogRecord/DeserializedLogRecord/IBufferedLogger. - AddCckrLogSampling registers one reservoir instance as both seams.
