Changes

• Add an includeUserQueriesForLookups parameter to the getQueries API: when includeUserQueries is false, restrict the returned user-defined queries to those that expose a primary key.
• Treat a query as a lookup target only when it has a real primary key — ignore synthetic/auto-added key columns, and exclude queries that fail to resolve.
• Cache each user query's has-primary-key result, keyed on the query's last-modified stamp, so repeat enumerations skip re-resolving queries already known to lack a key.
