Three progressive levels for gwbasic-compile: --warn: static analysis warnings (uninitialized variables, GOTO to nonexistent line, unreachable code detection). Zero runtime cost. --safe (implies --warn): runtime checked integer arithmetic via gw_int_add/sub/mul/neg matching real GW-BASIC overflow semantics, enhanced array bounds diagnostics with variable names and line numbers, GOSUB stack overflow diagnostics with source line reporting. --safe=sanitize (implies --safe): passes -fsanitize=address,undefined to gcc for full memory error detection. Also: fix pre-existing missing closing paren in array LET-to-integer codegen, add strpool_pin/unpin infrastructure, add compiler optimization flags and memory safety sections to roadmap. 72/72 interpreter tests pass. 64/64 eligible compiler tests pass in --safe mode.
