Subject: [PATCH] chore(tools): sync bat syntax with current word set

Alternations diffed against live WORDS output (304 words) plus
outer-interpreter tokens. Adds float transcendentals, double-cell
ops, pictured numeric, conditional compilation, string ops,
SEE/SEE-IR/DUMP/BYE/HELP, RP@/RDEPTH/.RS, REMEMBER/EMPTY/GILD,
DECIMAL/HEX, INCLUDE/INCLUDED, WITHIN, DEFER!/DEFER@, C,.
