Teach the boss cautions two silencers beyond the card killers

The Water removes every discard at blind start (blind.lua:208, returned
only after the fight), idling discard granters and payoffs alike; The
Eye blocks a repeated hand type outright (blind.lua:189/577), giving a
one-hand build exactly one shot. BOSS_KILLS entries now carry a tag SET
and their own factual phrase, since "debuffs X" stopped being the only
true sentence. The Arm and The Ox were chased and rejected -- level
drain does not touch the planet jokers, and The Ox fires on the
player's own hand choice, the same reasoning that rejected the Card
Sharp/Obelisk clash -- recorded in the BOSS_KILLS comment so nobody
re-adds them.
