### Purpose Hybrid RRF ranked rows within each route only by score. When multiple rows had the same route score, their RRF rank depended on the input bitmap iteration order and Java sort stability, while the final `topK` already used `score desc, rowId asc`. This PR makes the route-level RRF ranking use the same deterministic tie-break: `score desc, rowId asc`. It also adds regression coverage for tied route scores and verifies the resulting RRF contributions. ### Tests - `mvn -pl paimon-common -Dtest=HybridSearchRankerTest test` -- This is an automated message from the Apache Git Service.
