Does not predict endmoveheat effect of movement

```
It seems there is a problem with laser heatsinks and melee attacks - CG does not predict endmoveheat effect of movement

here it decided not to fire weapons during melee when it was percfectly acceptable and even desirable to do so
i also suspect that it would behave similary if mech has acepilot
```

Start by reproducing the logged attack-solution evaluation involving melee attacks, laser heatsinks, movement heat, and acepilot behavior. Trace where endmoveheat is considered in the prediction, then verify that the selected attack matches the reported acceptable-heat outcome and that the behavior is covered by a regression test.
