Thanks! What's super neat here is that I didn't have to build that. The WASI standard defines `fd_fdstat_get` which tells the binary the type of the file descriptor. For stdin/stdout/stderr I return that it is a "Character Device" (https://github.com/taybenlor/runno/blob/main/packages/wasi-motor/lib/wasi/wasi.ts#L484 https://github.com/taybenlor/runno/blob/main/packages/wasi-m...). QuickJS understands that means it's running in a TTY and so it emits all the right characters to do colouring. XTerm.JS then interprets those characters and displays the appropriate colours.
