### Rationale for this change Fixed-length byte-array constructors reject non-positive widths, but `PrimitiveNode.SetTypeLength` allowed an existing valid node to be mutated to zero or a negative width. The invalid node could then be serialized or passed to encoders. ### What changes are included in this PR? * Reject non-positive widths when mutating fixed-length byte-array nodes. * Leave non-fixed-width primitive nodes unchanged, preserving the existing no-op behavior. * Document the panic contract on the setter. ### Are these changes tested? Yes. The regression test covers zero and negative widths, verifies that failed mutations preserve the previous width, and checks the existing no-op behavior for other physical types. The full `parquet/schema` package passes. -- This is an automated message from the Apache Git Service.
