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. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

+# DarkForge ISO Builder
+
+Builds a bootable live USB/CD image containing the DarkForge installer and a minimal live environment.
+
+## Overview
+
+The ISO builder compresses the base system into a squashfs image, creates a UEFI-bootable ISO via xorriso, and includes the installer scripts for deploying DarkForge to disk.
+
+## Requirements
+
+- `mksquashfs` (squashfs-tools) — filesystem compression
+- `xorriso` — ISO9660 image creation
+- `mkfs.fat` (dosfstools) — EFI partition image
+- `mcopy` (mtools) — copy files into FAT images
+- A completed base system build (Phase 3)
+- A compiled kernel at `kernel/vmlinuz`
+
+## Usage
+
+```bash
+bash src/iso/build-iso.sh
+```
+
+Output: `darkforge-live.iso` in the project root.
+
+## ISO Layout
+
+```
+darkforge-live.iso
+├── EFI/BOOT/BOOTX64.EFI     # Kernel (EFISTUB boot)
+├── boot/cmdline.txt          # Kernel command line
+├── LiveOS/rootfs.img         # squashfs compressed root
+└── install/                  # Installer scripts
+```
+
+## Boot Method
+
+The ISO boots via UEFI only (El Torito with EFI System Partition). No legacy BIOS support. The kernel loads directly via EFISTUB.
+
+## Testing
+
+Test the ISO in QEMU:
+
+```bash
+qemu-system-x86_64 \
+    -enable-kvm \
+    -m 4G \
+    -bios /usr/share/ovmf/OVMF.fd \
+    -cdrom darkforge-live.iso \
+    -boot d
+```
