Add el_mem_check() to el_runtime.c: reads ELC_MAX_MEM_MB (default 512), checks RSS via getrusage (macOS bytes / Linux KB normalised to MB), prints a clear diagnostic to stderr and exits(1) if exceeded. Wire it into two places: - compiler.el: upfront check at --emit-header entry point - codegen.el: per-function check in the streaming loop after each el_arena_pop, so runaway growth is caught at the earliest function boundary rather than after the machine is already dying.
