The wire that was missing: `ForceThinker` re-prices its weight set by the tactic the coordinator put the force on, per force and per round, and scores every candidate with that. A test through the bot's own command path takes one hex under `Entrench` and a different one under `Withdraw`, and fails without this line. Change-Id: I2f526608f1d7a8079c28432a91115d43132775e0
