/**
 * Represents an operation to create or replace a branch within the Nereids module's plan structure.
 * <p>
 * This class extends {@link AlterTableOp} and encapsulates the logic for handling branch creation or replacement,
 * including branch name, operation flags (create, replace, ifNotExists), and associated options defined in
 * {@link BranchOptions}.
 * <p>
 * It also provides implementations for required methods such as SQL translation and legacy clause conversion.
