Vitals menu-bar monitor rebuilt in SwiftUI

The full story

This is a SwiftUI menu-bar activity monitor for macOS, modelled on the Vitals app and rebuilt from a static REA analysis of the shipped app, with no original source used. It groups helper processes under their parent app and shows live CPU, memory, disk, network and GPU use per app. It also lists development projects with their open ports, spots idle dev servers, shows what's keeping the Mac awake and flags sustained heavy use.
