spec(SHARD-WP-0005 T5): cache freshness & invalidation protocol (§8.8)

Fixes C-2 (invalidation). Per-binding modes (event-driven push / validator
poll / TTL), hybrid default, operational-envelope coupling (rate-limited
shards must not poll-per-read), single-flight coalescing + batched bulk
invalidation, freshness always represented in the provenance envelope.
