An editor for plain text where you can also seamlessly insert line drawings

new primitives for reading/writing files

These are like versions in nativefs, but only support absolute paths. I want to be thoughtful about the precise location at each call-site.

It's a little ugly that app.lua now has a dependency on file.lua. Or source_file.lua for the source editor.
