GUEST: step 0 — baseline snapshot

Created lib/guest/baseline/ with normalised scoreboards for all 11 guests:
lua 185/185, forth 64/64, ruby 76/76, apl 73/73, prolog 590/590,
common-lisp 309/309, smalltalk 625/629, tcl 3/4, haskell 0/18 programs,
js 94/148 (test262-slice), erlang 0/0 (suite all-zero).

Re-ran every conformance.sh and test.sh; refreshed each guest's own
scoreboard.{json,md} so per-guest scoreboard matches lib/guest/baseline/<lang>.json.
