This pull request enables predicate passthrough for the StreamingRepartition logical operator by implementing the LogicalOperatorSupportsPredicatePassThrough interface. This change allows filters to be pushed through repartitioning operations that only adjust block sizes without altering the schema. Additionally, a new test case has been added to verify that filters correctly push through StreamingRepartition. I have no feedback to provide as there were no review comments.

…oject#62347) ## Description StreamingRepartition only re-bundles rows into fixed-size blocks without modifying schema or row content. Filters can safely pass through it, same as the existing Repartition operator. This allows predicates to be evaluated earlier in the pipeline, reducing the volume of data that gets re-partitioned. ## Related issues > Link related issues: "Fixes ray-project#1234", "Closes ray-project#1234", or "Related to ray-project#1234". ## Additional information > Optional: Add implementation details, API changes, usage examples, screenshots, etc. Signed-off-by: You-Cheng Lin <mses010108@gmail.com>
