feat(query-core): add structuralSharing option to useQueries

[dagstuan]

🎯 Changes

Add a structuralSharing option to useQueries/createQueries/injectQueries that allows disabling structural sharing for the combined result. When set to false, the combined result will not use replaceEqualDeep for referential stability. Defaults to true.

Full disclosure: Docs were generated by Claude, all other implementation was done without AI.
