Ok, this sounds like a plausible direction — thanks!

It seems that Cursor is using Electron. I don't know about its internals (tried it a couple of times years ago), but after a quick look at the docs I've found this: https://www.electronjs.org/docs/latest/api/utility-process#u... which is a section describing `utilityProcess.fork(modulePath[, args][, options])`:

    env Object (optional) - Environment key-value pairs. Default is process.env.

I don't get why some unique-looking prefix/suffix would be needed there, though.
