dsh-sidebar-marks: Adding Marks to Conversations in the DSH Left Sidebar

DSH's `dsh-sidebar-marks` plugin adds conversation marks via CSS injection, addressing sidebar clutter and difficult navigation. Maintained by QIN-SMART, it supports Windows, macOS, and Linux, is released under the MIT license, and has zero runtime dependencies. After installation, the marks panel can be opened from the menu, a shortcut, or right-click. Core features include three marking styles: a light row background with adjustable intensity, a colored dot with selectable position, and an independent title font size.
