Added a comment in the Safe contract to clarify that the `s` value of ECDSA signatures is not enforced to be in the lower half of the curve. This note explains the implications of ECDSA malleability and reassures that existing mechanisms are in place to prevent duplicate signatures and replay attacks. No functional changes were made to the contract logic.
