v0.38.0

Focus of this release: smarter anomaly detection. Four new detectors/advisories drawn from real Valkey failure modes, one detection accuracy fix, and a build-system cleanup.

✨ New — Anomaly detection & advisories

• Replica full-resync failure loop (#373, valkey#1836) — Flags a replica that keeps failing full sync and reconnecting in a loop, instead of quietly churning. Surfaces the stuck replica before it burns bandwidth and delays replication indefinitely.
• Orphaned keys in unowned cluster slots (#376, valkey#539) — Detects keys living in hash slots the node no longer owns (e.g. after a resharding that didn't fully migrate), which are otherwise invisible and unreachable through normal cluster routing.
• appendfsync=always blocking advisory (#375, valkey#3515) — Raises a config hazard when appendfsync=always is set, since it fsyncs on the main thread for every write and can severely cap throughput. Called out so operators can make the durability-vs-latency tradeoff deliberately.
• Config-drift now covers encoding thresholds (#374, valkey#3479) — Extends config-drift detection to encoding-threshold settings (e.g. *-max-listpack-* / *-max-intset-*), catching silent memory/CPU regressions from drifted encoding limits.

🐛 Fixed

• Memory-overhead detector no longer false-alarms on underflowed samples (#372) — Underflowed memory readings are now skipped rather than treated as real overhead, removing spurious anomalies.

🔧 Changed / Internal

• Single multi-target Dockerfile (#379) — Consolidated Dockerfile.prod into one multi-target Dockerfile, simplifying the build matrix and the publish workflow. No change to published image behavior.
