reminded by semarie@, thanks!
use File::Temp for the index pages; specify why it's not using tmppath
we can't use the tmppath pledge promise as File::Temp checks whether /tmp exists. We could unveil("/tmp", "r") and use `tmppath', but it seem misleading. (noticed after semarie@ reminded me of `tmppath')
create temp files in /tmp and don't allow writes to "."
there's little point to use pledge/unveil and then allow the program to modify itself...
