# Reassemble the split release Catalog shards back into the single JSON
# document shape (version + surface_hash + source_hash + catalog + tools) that
# the policy jq queries consume.
#
# The Catalog is a committed global file (schema_catalog/catalog.json); each
# product's leaf ToolSpecs live in their own shard (schema_catalog/tools/*.json)
# so concurrent feature PRs only rewrite one shard. This helper merges the
# shards back into one document so existing jq queries keep working unchanged.
