DeepSeek Harness Plugin dsh-file-panel: Right-Side Session File Panel

`dsh-file-panel` is a right-side file panel plugin for DeepSeek Harness (DSH), maintained by `yu2025-luo` and licensed under the MIT License. This plugin addresses the cumbersome issue of manually locating file paths generated by agents in the `dsh` web GUI. It automatically tracks files created or downloaded during a session, displays them centrally in the right-side panel, and supports inline image previews, text content viewing, and metadata display, as well as features such as locating files in the file manager, opening them with default applications, and copying absolute paths. Installation requires adding the plugin via a command and restarting the `dsh web` server. Its security boundaries are strict: the RPC channel is restricted to local loopback address calls, file reading is limited to observed paths only, and the panel state is cleared upon process restart without scanning historical files.
