Expose per-ring `dropped_count` / `lost_count` atomics in SubRingHeader (placed inside existing write_pos cache-line padding — no sizeof change, no new coherency traffic). Publisher bumps dropped_count on the self- repair / drop path; Subscriber bumps lost_count at each loss site. New SharedRegion::stats() returns a RegionStats snapshot: per-ring state, in_flight, write_pos, dropped_count, lost_count plus aggregates (total_writes, total_drops, total_losses, live_rings, approximate pool_free). Safe under live traffic. Python bindings expose RingStats, RegionStats, and SharedRegion.stats() so external monitoring can read counters without a CLI.
