Fixes #37644 Support evaluating IFNULL/COALESCE expression projections after aggregation merge Add support for evaluating expression projections that wrap aggregation functions, such as IFNULL(SUM(...), 0) and COALESCE(...), after aggregation results are merged. Track derived aggregations for supported expression projections in ProjectionEngine, evaluate them during both memory and stream group-by merging, and limit expression extraction to supported functions to avoid unsupported in-memory SQL evaluation. Also add regression tests covering projection extraction, expression evaluation, and end-to-end group-by merge behavior. --- Before committing this PR, I'm sure that I have checked the following options: - [ ] My code follows the [code of conduct](https://shardingsphere.apache.org/community/en/involved/conduct/code/) of this project. - [ ] I have self-reviewed the commit code. - [ ] I have (or in the comment I request) added corresponding labels for the pull request. - [ ] I have passed Maven check locally: `./mvnw clean install -B -T1C -Dmaven.javadoc.skip -Dmaven.jacoco.skip -e`. - [ ] I have made corresponding changes to the documentation. - [ ] I have added corresponding unit tests for my changes. - [ ] I have updated the Release Notes of the current development version.
