test(bot-mode): trim the author and loop-guard suites to their invariants

Keep one or two behaviour tests per seam (author reset on a cached agent, forged
_turn_author refused, guard trips and cools, single charge on the busy path) and
drop the parser/setting enumerations. a2a_key goes with them: nothing in this PR
reads it; the honcho follow-up that does can bring it back with its consumer.
