### What problem does this PR solve? Issue Number: N/A Related PR: #65436 Problem Summary: A top-level NESTED search currently maps matching child elements to parent rows but does not aggregate element scores into CollectionSimilarity. If score() pushdown is allowed, the parent rows can materialize zero scores. Reject top-level NESTED + score() in the FE pushdown rule and add a BE guard until nested score aggregation is implemented. ### Release note None. ### Check List (For Author) - [x] Test: FE unit tests - [x] Test: FE build - [ ] Test: BE build in progress - [x] Behavior changed: unsupported top-level NESTED + score() now returns an explicit error - [x] Does this need documentation: No -- This is an automated message from the Apache Git Service.
