Initial commit: DarkForge Linux — Phases 0-12

Complete from-scratch Linux distribution targeting AMD Ryzen 9 9950X3D +
NVIDIA RTX 5090 on ASUS ROG CROSSHAIR X870E HERO.

Deliverables:
- dpack: custom package manager in Rust (3,800 lines)
  - TOML package parser, dependency resolver, build sandbox
  - CRUX Pkgfile and Gentoo ebuild converters
  - Shared library conflict detection
- 124 package definitions across 4 repos (core/extra/desktop/gaming)
- 34 toolchain bootstrap scripts (LFS 13.0 adapted for Zen 5)
- Linux 6.19.8 kernel config (hardware-specific, fully commented)
- SysVinit init system with rc.d service scripts
- Live ISO builder (UEFI-only, squashfs+xorriso)
- Interactive installer (GPT partitioning, EFISTUB boot)
- Integration test checklist (docs/TESTING.md)

No systemd. No bootloader. No display manager.
Kernel boots via EFISTUB → auto-login → dwl Wayland compositor.
