an addon loop reports instead of hanging the whole survey

- every addon VM runs under an instruction bound, so a non-terminating loop becomes a report — and the bound promptly caught a landed fix that had been left switched off
- an unrecognised unit token raises the client's own "Unknown unit name" error instead of answering nil
- GetBindLocation answers from a real bind point, and RequestTimePlayed round-trips with TIME_PLAYED_MSG — both halves or neither
