Bites the DSH: A Read-Only Session Replay Tool for DSH WebUI

Bites the DSH is a plugin for DeepSeek Harness (DSH) that converts the native session interface into a read-only playback view. It supports pausing, fast-forwarding, rewinding, step debugging, speed selection, and script-based timeline control. The plugin provides a native entry point and a `ctx.sessionPlayback` interface, enabling safe review or reproduction of session workflows in read-only mode, suitable for DSH development and debugging.
