Refactor Vue <-> Editor <-> CodeMirror code.
Introduce Pinia store to keep global state, in order to get rid of a lot of event juggling between Editor class/child components and the root App component.
* Add support for opening settings dialog in the webapp
* Add tests for settings dialog
* Hide stand-alone app specific settings in web app
* Remove debug log
* Implement Buffer class in main process that watches for changes to the file, and notifies the editor in the renderer process so that it can update the buffer.
* Add Editor.setReadOnly() method
* Add dummy onChangeCallback function
* Remove debug logging
* Move windows.darkMode -> window.heynote.themeMode
* Only add UpdateStatusItem if window.heynote.autoUpdate is set
* Update Vite
* Implement web version of Heynote.
Add a child vite project in ./webapp/ that is Heynote running within a browser. Imports almost all code from ../src/ and only adds a thin bridge that corresponds to the API between the Electron main process and the app code.
* Remove commented out tag
* Specify publicDir in vite config, instead of using a symlink
* Add webapp_dev npm command to package.json
* Add npm run command: webapp:build
* Add resolve alias '@' that points to project root.
Move assets file from public to assets in order to let Vite/Rollup handle bundling.
