dsh-visible-action-row: Action bar for each message no longer requires hover

Native to DSH, action bars containing copy, timestamps, etc., are only persistently visible on the latest messages; historical messages only display these bars upon hover. The plugin **dsh-visible-action-row** (maintainer: Bobnemimimmi, MIT, v0.2.0, Client-side) uses a single scoped CSS rule to override opacity, making action bars for all messages always visible. It reuses native content, positioning, and rendering without adding new DOM elements, configuration options, or a backend. The README provides four installation methods (npm, Desktop, GitHub, and local directory), as well as uninstallation and migration commands for version 0.1.x. It has been verified on Desktop version 0.2.1-rc.5 and Web version 0.2.2-alpha.2, and explains compatibility checks for three frontend anchors.
