Build me a desktop app called Collaborator, a place where I can work with agents side by side with my files and terminal. I want one window with a left sidebar for my local folders and a big infinite canvas in the main area where I can pan, zoom, and place tiles. Double click the canvas to open a terminal tile, drag files from the sidebar onto the canvas to open them as editable note, code, or image tiles, and keep everything synced to the local files on disk.

It should feel like a real workspace for agentic coding, with a markdown editor, code editor, image preview, and terminals that keep running even if I move things around. Let me switch between multiple workspaces, search files, rename, create, delete, and drag things into folders. Make it work on macOS, Windows, and Linux, and store all app state locally. If you need to check current docs for any libraries or desktop APIs, go ahead and look them up online.
