genmap: default genome reservation 0x70000 words (the genome had 197 words left); the map constants in rt.zc and the README table move by 0x8000; gc.zc's reclaim bound is 900 (937 with the heap higher, 952 before) and the run-only section rewrites whatever its number

 the numbers describe the default build's initial reservations. compact compiler and run-only maps start with smaller reservations and also support growth. `build/bin/genmap` writes matching layouts (see "smaller machines"); `--preset fixed` retains the older bounded heap for compatibility. the host answers `core.syscall(9, k)` with facts about the map (0 total words, 1 heap start, 2 heap end for now, 3 bytes). argument 4 requests memory growth, and argument 5 changes the growth limit within the host's backing constraints.
