Part of #23494.
repartition/mod.rs. Single child + Partitioning (RoundRobin/Hash/Range/Unknown) inlined from proto-models; hash/range exprs via the ctx; split-point ScalarValues via proto-common.
Follow the pattern in #23494 (reference impl: #23495 / ProjectionExec; full end-state draft: #23496). Add try_to_proto inside impl ExecutionPlan for X, add the inherent X::try_from_proto, repoint the decode arm, and delete the old central arm in the same PR (that is the proof the hook is reached). Keep the wire format byte-for-byte identical.
