VM: add string concatenation in OP_ADD, len() built-in, multi-arg print/println, undefined variable detection, and GC via OP_NOP. Parser: fix operator precedence by splitting into parse_expr (+,-) and parse_term (*,/) so 8 + 2 * 4 = 16 instead of 40. Compiler: emit OP_NOP at start of NODE_BLOCK to trigger GC.
