go: port combat, chase driver, traps, zapping, death and scores

- fight.c in full: fight/attack with all eight special monster attacks
  (aquator rust, ice freeze, rattlesnake poison, wraith/vampire drains,
  flytrap hold, leprechaun/nymph theft), swing, roll_em dice parsing
  (with a C-semantics atoi — Go's strconv rejects '1x4/...'), hit/miss
  message variants, killed, remove_mon
- chase.c completed: runners, move_monst, relocate, do_chase with
  dragon breath, chase target selection (C's dead oroom comparison in
  relocate is preserved as-is)
- move.c in full: do_move with passgo turning, all eight traps,
  rndmove, rust_armor
- sticks.c completed: do_zap (all 14 sticks), drain, fire_bolt with
  wall bounces; weapons.c completed: missile/do_motion/fall/wield
- rip.c: death tombstone, total_winner, killname; C exit() becomes a
  gameEnd panic that Run will recover
- score.go: top-ten scoreboard as a gob file with lock-file protocol
  replacing the XOR-encrypted C format
- wizard.c: whatis/set_know/teleport; daemons.c stomach
- monster bestiary moved to per-game state (C mutates the flytrap
  damage string during play)

Tests: combat math, kill/removal bookkeeping, monster chase pursuit,
death unwinding, scripted-input headless terminal.
