/**
 * Bootstrap for restruct/docsys-tools (umbrella package)
 *
 * Defines system tool paths for tools that are NOT bundled but expected
 * to be installed on the system. Sub-packages handle their own bootstrapping:
 * - restruct/cpdf-static → CPDF_PATH
 * - restruct/wkhtmltopdf-static → WKHTMLTOPDF_PATH, WKHTMLTOPDF_DOCKER_IMAGE
 * - restruct/xpdf-static → XPDF_BIN_DIR
 * - restruct/dot-static → GRAPHVIZ_DOT_PATH
 *
 * This bootstrap defines:
 * - GS_PATH (Ghostscript)
 * - CONVERT_PATH (ImageMagick/GraphicsMagick)
 * - SOFFICE_PATH (LibreOffice headless)
 *
 * Priority for each:
 * 1. Already defined constant
 * 2. Environment variable
 * 3. macOS: Homebrew paths (ARM first, then Intel)
 * 4. Linux: standard system paths
