**Add single-command bootstrap and fix lfs user permission issues**
### Changes:
- Added `toolchain/bootstrap.sh`: Single entry point that runs the entire Phase 0:
- Tears down and recreates the loopback filesystem (fresh start)
- Sets up environment, downloads sources
- Copies toolchain scripts to `$LFS/sources/toolchain-scripts/` (lfs-accessible)
- Runs `build-all.sh` as lfs user automatically
- Rewrote `toolchain/scripts/000-setup-disk.sh`:
- Now tears down existing build (unmount + delete image) on every run
- No longer exits early if mount exists — always gives a fresh filesystem
- Fixed `toolchain/scripts/build-all.sh`:
- Log directory changed from `${SCRIPT_DIR}/../logs` to `${LFS}/sources/logs/`
- Fixes "Permission denied" when lfs user can't write to danny's home dir
### Plan deviation/changes:
- Scripts are now copied to `$LFS/sources/toolchain-scripts/` rather than run from
the git repo. This avoids all permission issues with the lfs user not being able
to read /home/danny/. The git repo remains the source of truth.
### What is missing/needs polish:
- None

# DarkForge Linux — Phase 0: Full Bootstrap
# ============================================================================
# Purpose: Single entry point that runs the entire Phase 0 bootstrap:
# 1. Tear down & create fresh loopback filesystem
# 2. Set up directory structure, lfs user, env files
# 3. Download source tarballs
# 4. Copy toolchain scripts to $LFS so lfs user can access them
# 5. Launch build-all.sh as the lfs user
#
# Usage: sudo -E bash toolchain/bootstrap.sh
# (run from the project root, e.g. /home/danny/darkforge)
#
# Inputs: LFS (default: /mnt/darkforge)
# Outputs: A complete cross-toolchain and temporary tools on $LFS
# Assumes: Running as root on Arch Linux, internet access
