When set, the full archive contents are extracted into + this directory, preserving sibling files (`lib/`, `share/`, `libexec/`, etc.). Use this for + toolchains that ship as a pre-built directory tree where the binary resolves paths relative to its + own location (Neovim, Go, Node, Flutter, Zig, many language servers).
