# DarkForge Linux — Phase 0, Chapter 7: Cleanup Temporary Tools
# ============================================================================
# Purpose:  Clean up the temporary toolchain now that we have native tools
#           in the chroot. Remove documentation, static libraries, and the
#           cross-compiler tools directory.
# Inputs:   None
# Outputs:  Cleaned filesystem, removed /tools
# Assumes:  Running inside chroot, all chroot builds (024-030) complete
# Ref:      LFS 13.0 §7.13
# ============================================================================
