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 Linux — Phase 0, Chapter 7: Create Essential Files and Symlinks
+# ============================================================================
+# Purpose:  Create the essential system files (/etc/passwd, /etc/group,
+#           log files) and symlinks that programs expect to exist.
+#           This script runs INSIDE the chroot environment.
+# Inputs:   None (creates files from scratch)
+# Outputs:  /etc/passwd, /etc/group, log files, essential symlinks
+# Assumes:  Running inside chroot (script 023 completed)
+# Ref:      LFS 13.0 §7.6
+# ============================================================================
