Subject: [PATCH] test(#2185): cover Linuxbrew + custom-prefix Cellar paths in
 normalizeNodePath
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds the Linuxbrew Cellar layout (/home/linuxbrew/.linuxbrew/Cellar/...), a
post-version-bump path, a node@version formula, and a custom HOMEBREW_PREFIX —
all mapping to the stable <prefix>/bin/node symlink. Mirrored in both
consolidated describe blocks.
