dsh-session-title-pattern: Automatic Management of DSH Session Titles

The DeepSeek Harness (DSH) plugin `dsh-session-title-pattern` automatically generates formatted session titles, standardizing them into the “Date | Type | Topic” format. It supports custom templates, specifying a generation model, scheduled recalculation, and manual renaming, and can expand title display width by injecting CSS. After installation, configure the recalculation interval, model, and template. It is suitable for developers who need to increase information density in the sidebar.
