v0.18.0: "Ship It" -- Final Subsystem Integration

VeridianOS v0.18.0 wires ~40 previously disconnected subsystems into a cohesive, production-ready OS experience. Every subsystem was already implemented across Phases 0-8; this release connects them to the user-facing shell and desktop environment. Implemented across 8 independently releasable waves with no architectural changes.

Highlights

  • 128 shell builtins (up from 65) -- 63 new commands across 10 categories
  • 9 desktop applications (up from 7) -- web browser and PDF viewer added
  • 8 settings panels (up from 5) -- audio, Bluetooth, and power management panels
  • Init system activation -- 8 services registered and auto-started at boot
  • System tray expanded -- 6 indicators: network, CPU, memory, volume, battery, clock
  • CI coverage fix -- cargo llvm-cov graceful degradation for bare-metal kernel on host target
