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.

+# DarkForge Kernel Configuration
+
+Hardware-specific Linux 6.19.8 kernel configuration for the target machine.
+
+## Target Hardware
+
+- **CPU:** AMD Ryzen 9 9950X3D (Zen 5, 16C/32T)
+- **GPU:** NVIDIA RTX 5090 (Blackwell) — out-of-tree nvidia-open modules
+- **NIC:** Realtek RTL8125BN 2.5GbE (R8169 driver)
+- **NVMe:** Samsung 9100 PRO (PCIe 5.0)
+- **Motherboard:** ASUS ROG CROSSHAIR X870E HERO
+
+## Key Choices
+
+| Feature | Config | Why |
+|---------|--------|-----|
+| CPU optimization | `CONFIG_MZEN4=y` | Closest kernel config symbol; real znver5 from CFLAGS |
+| Scheduler | EEVDF (default) | Modern, built-in since 6.6 |
+| Preemption | `CONFIG_PREEMPT=y` | Full preemption for gaming latency |
+| Timer | `CONFIG_HZ_1000=y` | Lowest latency tick rate |
+| CPU governor | `CONFIG_CPU_FREQ_DEFAULT_GOV_SCHEDUTIL=y` | P-State EPP integration |
+| NVMe | `CONFIG_BLK_DEV_NVME=y` | Built-in (root is on NVMe) |
+| GPU | nouveau disabled | nvidia-open kernel modules used instead |
+| Boot | `CONFIG_EFI_STUB=y` | Direct UEFI boot, no bootloader |
+| Network | `CONFIG_R8169=y` | Realtek 2.5GbE |
+| Hibernation | `CONFIG_HIBERNATION=y` | 96GB swap partition |
+| Bluetooth | `CONFIG_BLUETOOTH=n` | Disabled |
+| WiFi | `CONFIG_WIRELESS=n` | Ethernet only |
+
+Every non-default option in `config` has an inline comment explaining the rationale.
+
+## Usage
+
+```bash
+cp config /usr/src/linux-6.19.8/.config
+cd /usr/src/linux-6.19.8
+make olddefconfig    # fill new options with defaults
+make -j32            # build with 32 threads
+make modules_install
+cp arch/x86/boot/bzImage /boot/vmlinuz
+```
+
+## NVIDIA Driver
+
+The RTX 5090 requires nvidia-open kernel modules (570.86.16+). These are built out-of-tree after the kernel:
+
+```bash
+cd /usr/src/nvidia-open-570.133.07
+make -j32 modules KERNEL_UNAME=$(uname -r)
+make modules_install
+```
+
+The modules are loaded at boot via `/etc/rc.conf`:
+
+```bash
+MODULES=(nvidia nvidia-modeset nvidia-drm nvidia-uvm)
+MODULE_PARAMS=("nvidia-drm modeset=1")
+```
