v0.3.0 — entitlements catalog in PublicPoliciesResponse

Mirrors keysat 0014 + TS/Rust SDK 0.3.0. PublicPoliciesProduct
gains entitlements_catalog: list[EntitlementDef] with slug + name +
description. SDK consumers' in-app tier pickers can render display
names + tooltip descriptions instead of raw slugs. Empty list on
legacy products without a catalog. No breaking change.
