A hello-world web app in Go, for FadeHost app hosting.
Deploy it from the panel with no start command and no build command: the
runtime sees the go.mod, compiles the module and runs the binary.
It reads the port from the PORT variable, which FadeHost sets for every
app, and prints the result of a request to itself once it is listening.
PORT=8080 go run .
