get_catalog_entry

Fetch one static spec catalog record by `kind` + `id` (one faceted tool replacing the 15 `get_*-by-id` spec-introspection tools). Reads `@unified-product-graph/core`. `id` is the record identifier for that kind: `playbook`/`framework`/`lens`/`scale`/`anti_pattern`/`tree_pattern`/`domain_ring`/`region`/`approach` take their record id; `entity_meta` takes an entity-type name; `edge_type` takes an edge-type key; `lifecycle`/`type_label` take an entity type; `domain_guide` takes a domain id; `template` takes a template id. Use `list_catalog` to enumerate a kind.
