dsh-replay-theater: Replaying DeepSeek Harness Sessions with Original Token Timing

The dsh-replay-theater plugin for DeepSeek Harness (DSH) addresses the lack of visualization for exact token arrival intervals in session logs. It provides an inline playback theater and supports token-by-token replay according to the original millisecond timing, with features such as play, pause, single-step, variable speed, muted compression, and comparative runs. After installation, users can access controls through the Theater tab on the side of the session page. The tool is primarily used to analyze reasoning processes, debug streaming output, or demonstrate agent behavior, and is compatible with dsh version 0.2.0-rc.2.
