📝 Summary

• Hovering u.id in queries using FROM "my.table" u or FROM "my.db".users u fails to show column details because alias lookup flattens quoted identifier boundaries.
• Resolve alias targets containing literal dots through their existing segmented table paths. Keep ordinary alias lookup behavior and public context types unchanged.
• Cover quoted table/catalog names alongside colliding nested namespaces, and prevent missing columns from resolving through a different nested table.
