AI doesn't account for TSM when calculating acceptable heat

Reported by Harkonnen in closed-3437 on RT discord:

```
acceptable heat: 31.5
while this is probably a good value for most mech, there is TSM. this basicaly means that AI purposely avoids activating TSM on punchbots, wich is wrong as fuck
```

No source file, test, or entry point is named. Start by locating the AI's acceptable-heat calculation and its handling of TSM, then reproduce the punchbot scenario described in the report. Done means the AI accounts for TSM when deciding whether a punchbot's heat is acceptable and the behavior is covered by a regression test if the project has a relevant test suite.
