Conversation
When a .md file is set to open with the desktop app (e.g. via OS file association), the file path is passed as a command-line argument. Previously the app ignored it and always showed the landing page, requiring the user to drag-and-drop or import the file manually. This change reads the argument in main.js using Neutralino.filesystem .readFile and injects the content into the editor on startup. filesystem.readFile is also added to nativeAllowList in neutralino.config.json to permit the API call.

Problem
When a .md file is associated with the desktop app and double-clicked, the OS passes the file path as a command-line argument. The app was ignoring this and always showed the landing page, forcing the user to manually drag-and-drop or import the file.
Solution
In main.js, added a loadInitialFile function that reads NL_ARGS to find any .md or .markdown file path, uses Neutralino.filesystem.readFile to load its content, then injects it into the editor on startup.
In neutralino.config.json, added filesystem.readFile to nativeAllowList to permit the API call.
