v7.30.19

Superseded by v7.30.20 for packaged installs. v7.30.19 introduced the structured product knowledge catalog, but packaged updates did not copy the new product_knowledge/ package. Use v7.30.20 or later for npm/packaged installs.

Product capabilities now live in a structured, validated catalog with source-linked capabilities, safety metadata, live-state guidance, and read-only discovery tools. This release adds nexo_product_capabilities, nexo_capability_explain, nexo_product_answer, nexo_product_surface_status, and nexo_product_knowledge_validate, while preserving legacy system-catalog names such as nexo_provider_models, nexo_credits_cloud, and nexo_email_managed_agent_mailbox.
