Summary

Sets up and verifies the development environment for this Electron Markdown editor, and documents non-obvious Cursor Cloud run caveats.

• Adds AGENTS.md with a ## Cursor Cloud specific instructions section covering how to run the app, the display caveat, ignorable dbus noise, and the absence of lint/test scripts.
• Update script configured separately as npm install (minimal dependency refresh).

What was verified

• npm install installs all dependencies and downloads the Electron binary.
• npm start launches the Electron desktop app on the VNC display (:1).
• Hello-world: typed Markdown (heading, bold/italic, list, JS code block) into the editor and confirmed the live preview pane renders it with formatting and syntax highlighting.

Walkthrough

Notes

• No lint or test scripts exist in this repo (no ESLint/Prettier/test framework).
• AI features are optional and require an external OpenAI-compatible endpoint; not needed for core editing/preview.
