- eslint 9 with flat config, prettier 3, eslint-plugin-prettier 5 - tests migrated from tap to node:test - CI on Node 20/22/24 (16 and 18 are EOL), actions/setup-node v6 - regenerated package-lock.json, which had lost the fsevents entry and made `npm ci` fail in the release workflow Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01YEboe44Fee8PMf9Zv5kbqe

Fixes #205.
Security fix
decompress(used only by the Windows postinstall to extract Sysinternals'DU.zip) is affected by GHSA-mp2f-45pm-3cg9 and has no patched release. It is removed.The archive is now read with the
tar.exe(bsdtar) that ships with Windows 10+, called by full path. tar is only used to list the archive (-tf) and to stream individual entries to stdout (-xOf), never to write to disk:du.exe,du64.exe,du64a.exeandEula.txtare written by name intobin/, and nothing else in the archive is touched. Entry paths,..components and symlinks inside the archive therefore cannot decide where anything is written.A first attempt that let
tar -xextract into a temp directory turned out not to be enough: Windows' bsdtar followed a symlink entry and wrote outside the target. The zip-slip fixture includes that case.Tooling (dev only, no effect on the published package)
