Remove conditional logic and consolidate NODE_FOR implementation to use variable-sized nodes exclusively. This eliminates dual code paths and completes the NODE_FOR migration. Changes: - inline new_for_var into new_for, remove p->var_nodes_enabled condition - remove new_for_var function and forward declaration - enhance gen_for_var with complete for-loop implementation from for_body - remove codegen_for and for_body functions - remove NODE_FOR case from main codegen switch (traditional cons-list path) The for-loop implementation preserves Ruby's each-based semantics with proper block scoping, argument handling, and loop control (break/next/redo) while providing better memory efficiency through variable-sized nodes.
