[BUG] Garbo buffs full day of Merry Smithsness even when not using Half-A-Purse

[Shiverwarp]

Right now we just assume purse usage based on this:

let cachedUsingPurse: boolean | null = null;
export function usingPurse(): boolean {
  if (cachedUsingPurse === null) {
    cachedUsingPurse =
      myInebriety() <= inebrietyLimit() &&
      (!have($item`latte lovers member's mug`) ||
        (!have($familiar`Robortender`) && !have($familiar`Hobo Monkey`)) ||
        !canAdventure($location`The Black Forest`));
  }
  return cachedUsingPurse;
}

However, we now have more possibly profitable offhands than half-a-purse during barf turns (snowglobe particularly)

So we end up buffing smithsness even though our outfit won't be wearing half-a-purse.

A hypothetical solution is to attempt to build our barf outfit here (with stand-in values for half-a-purse if we do not currently have smithsness), and if the outfit includes half a purse, we can then assume we'll be wearing it enough for smithsness buffing
