[enhancement] zig.hook build printing

[mgord9518]

As it is currently, zig.hook spams hundreds of newlines while building due to its build graph, this leads to a subpar build output. To prevent this, TERM=dumb should be set, and --verbose should be appended to the zig build command

I've tested this on a local derivation but I'm unsure how to actually apply it to the existing hook, which is why I haven't sent a PR
