Vest: a day that lost to the bot's limit stops, even with Vest room left

The daily-loss room on Vest was min(the stage's limit, balance − Vest's
floor), which ignored the day's losses against the bot's own limit. With
the type's $1,229 under Vest's 3% ($1,500), five 50k evals that had
lost $1,111.65 today still saw $388 of room and traded again. The room
is now min(limit + the day's realized loss, balance − floor).
