> Add a consolidated SQL golden test, show-commands.sql, for SHOW CATALOGS,
> SHOW COLLATIONS and SHOW CURRENT NAMESPACE, including the CURRENT DATABASE and
> CURRENT SCHEMA aliases. Generate both execution-result and analyzed-plan
> golden files.
> Cover 11 SHOW scenarios:
> * Catalogs: catalog loading, case-insensitive wildcard filtering and no-match
> patterns.
> * Current namespace: the session catalog's default and changed databases, a
> catalog with
> an empty default namespace, a quoted multipart V2 namespace and the
> DATABASE/SCHEMA aliases.
> * Collations: a bounded UTF8/ICU wildcard and alternation selection, exact
> matching without
> LIKE and a no-match pattern.
> These tests protect output schemas, returned values and analyzed command
> nodes without
> changing runtime behavior. Use a bounded collation selection rather than
> snapshotting
> the entire ICU inventory.
