dsh-plugin-translation: DeepSeek Harness Translation Toolkit

`dsh-plugin-translation` is a translation toolkit designed for DeepSeek Harness (DSH) agents, aimed at simplifying long-text translation workflows. This plugin provides multiple core functions via the `translate_kit` tool: using `segment` for text chunking; utilizing `glossary` series tools to extract, maintain, and perform consistency checks on glossaries; employing `check` for QA on numbers, brackets, length ratios, and punctuation between source and target texts; providing guidelines for formal, conversational, or technical registers via `tone`; and using `memo` series tools to persistently save and retrieve translation memories within the session workspace. Installation requires executing the specified command and restarting DSH, at which point the tool is automatically registered. File operations are restricted to the session workspace to ensure path safety.
