@oh-my-dsh/dsh-accessibility: Accessibility Assistance and Diagnostics Plugin for DeepSeek Harness

`@oh-my-dsh/dsh-accessibility` is a DeepSeek Harness (DSH) accessibility companion tool maintained by `omdsh-dev`. It provides, as a plugin, screen reader guidance, 17 semantic diagnostics (covering landmarks, controls, ARIA, and more), and an experimental conversational reading view. The tool runs through DSH's slot mechanism and leverages structured snapshots to help developers validate interface semantics, making it well suited for manual review and evidence collection within DSH environments. After installation, diagnostics can be run and the reading view can be loaded from Settings.
