dsh-thinking-token-stat: DeepSeek Harness Thinking Token Statistics Plugin

`dsh-thinking-token-stat` is a DeepSeek Harness plugin developed by Six6stRINgs, designed to overcome the limitations of turn-level statistics by providing session-level reasoning token analysis. It leverages session projection to visually display the total thinking tokens, reasoning output proportion, and per-turn details in the Composer Dock. It supports filtering by turn status (reported / inferred / uncounted) and includes jump buttons for quickly locating content. Values are displayed in K format, estimates are marked with `~`, and it maintains persistent calculations for the entire session.
