Research direction

Start at gnark-crypto's bls12381G1.SetBytes implementation and compare its validation with kilic's implementation. Confirm how an all-zero serialized point is handled and identify the existing tests for point deserialization, if present. Done means the all-zero array is rejected as an invalid point without breaking valid serialized points.

Written by the indexing model from the issue text.

Description

kilic's implementation instead fails since it realises that the point is not on the curve.
