dsh-llm-hub: Filling the Missing Half of the DSH Model Page That Official Adapters Omit

The `dsh-llm-hub` plugin aims to supplement the missing functionality of the official DeepSeek Harness (DSH) adapter. Its core features include model directory fetching, always-visible balance/quota display, gateway reachability probing and status monitoring, usage statistics, and CSV export. It also supports silent filtering of unavailable providers and automatic registration of external agent tools. Installation requires running the specified command and updating the configuration, followed by a restart to apply changes. The plugin is licensed under MIT, has zero dependencies, and offers key parsing, secure same-origin reads, and non-breaking modifications.
