Pull Request Overview

This PR decouples DynamicFilterService from SqlQueryExecution and ensures that once a query’s final info is set, subsequent updates return the existing info.

• Change registerQuery signature to accept Session and PlanNode instead of SqlQueryExecution
• Update SqlQueryExecution to call the new registerQuery overload
• Modify QueryStateMachine.updateQueryInfo to reuse an already-set final QueryInfo

• Consider adding a unit test to verify that updateQueryInfo returns the existing final QueryInfo when finalQueryInfo is already set to prevent regressions in this new behavior.

[nitpick] Extract getQueryPlan().orElseThrow().getRoot() into a local variable to avoid repeated Optional unwrapping in the method call for clarity and potential reuse.

Suggested change

	dynamicFilterService.registerQuery(getSession(), getQueryPlan().orElseThrow().getRoot(), plan.getRoot());
	var queryPlanRoot = getQueryPlan().orElseThrow().getRoot();
	dynamicFilterService.registerQuery(getSession(), queryPlanRoot, plan.getRoot());
