vecnode/dsh-editor

Editor: a CodeMirror 6 text/code editor tab type for the vncode right bar (dsh-rightbar). Opens text files editable instead of in the read-only preview - Markdown included, with a Preview/Edit toggle between the editor and the rendered view - starts a blank document from the tab strip's + control, names and creates new files through the shared dsh-modal dialog, and saves through an authenticated plugin route. The editor follows the app's light/dark theme, and the rendered Markdown page resets what the preview's plain-text scrollport imposes (its hard-break whitespace and mono font). Languages are mapped by extension - javascript/typescript, json, markdown, python, html, css and yaml from the vendored CodeMirror build, plus shell, PowerShell, batch, Rust and TOML as CM5-style stream modes - and EVERY lookup goes through one guard, so an engine older than this bundle opens the document unhighlighted and warns with the rebuild command instead of killing the tab. Alpha.
