Part of #23494.
datafusion-datasource-parquet. Like the simple scans plus the pushdown predicate (via ctx.encode_expr/decode_expr) and TableParquetOptions (via proto-common); rebuild the reader factory from ctx.task_ctx().runtime_env(). Blocked by #23497.
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.
