RESERVE_NAME
List of reserved JWT claim names that cannot be used as custom claims.
These claim names are automatically managed by the SDK during JWT creation and signing. Custom claims using these names would conflict with the standard JWT structure and security model:
sub (Subject): The user identifier for whom the JWT is issued
exp (Expiration Time): When the JWT expires
iat (Issued At): When the JWT was created
nbf (Not Before): When the JWT becomes valid
iss (Issuer): Who issued the JWT
challenge: Internal claim containing the cryptographic challenge
