What

The background classifier that generates recaps of project threads has had its "turn brief" summarization removed. It no longer computes this summary, no longer logs a turnBrief field on the tengu_bg_classify event, and no longer emits the separate turn_brief telemetry event.

Why

This rolls back a feature that had been added but was not yet fully wired up, cleaning up code and telemetry that were not being put to use.
