spec(SHARD-WP-0005 T8): tenant isolation of derived tier + history scaling

Fixes B-3/C-3. §9.1 structural per-tenant partitioning of the derived tier
(no shared cross-tenant cache; read-time filtering as defence-in-depth;
reconciles I-2+L5 per partition); new invariant I-13. §8.1 history stays
recoverable AND bounded (gc/repack, squash-compaction of churn preserving
recoverable endpoints, per-shard offload, anti-abuse hooks).
