What probably matters to youSection of the release

A new run-deduped cache plus a server-backed tool-count path can replace local estimation of tool definition token counts when analyzing context usage, falling back to the previous local estimator on error or when the tengu_peppy_zephyr gate is off. The feature is still gated off by default.
