Get Publish History

Per-version publish history for a product, derived from catalog_publish_records (each record pins product_version and carries publish_outcomes[target_key][env]).

Returns the latest SUCCESSFUL publish per (version, target_key, env) as {key, history: [{version, target_key, target_env, target_name, published_at}]} — drives the per-version “where published” badges on the product detail page. Single-product query, indexed by (organization_id, product_key).
