Review Comment:
Fixed in 1e88ec405d3. FE predicate conversion now runs in timestamp-repair
mode per predicate: timestamp-dependent leaves are withheld, safe non-timestamp
predicates are retained, AND siblings remain pushable, and mixed OR expressions
remain residual. JNI keeps the FE-approved safe predicate list instead of
clearing all filters. Added converter coverage for id = 7 retention and
timestamp residual behavior; FE unit tests and the Paimon timestamp regression
suite pass.
