`$HOME` env overriding makes Vite+ stuck stuck in an infinite loop, especially for Agents use

[liangmiQwQ]

Describe the bug

The current vp would find executable node with ~/.vite-plus dir. However, if we override $HOME environment var to a empty / no-vp dir, vp would download another node version.

And it causes problems, Vite+ also has an VITE_PLUS_TOOL_RECURSION env var, and if it is greater than 0, vp would pass through commands to node installed by vp including the downloading node program mentioned above. And an infinite loop happens here (as run node will trigger download node program over and over again).

The conditions that triggered it sounded very extreme but actually quite common. $HOME overriding usually happens for e2e tests in global cli projects, and if we use agents like Claude Code, Open Code which based on Node.js, and try to run tests inside, it's easy to trigger this case.

A possible solution is to find node by the getting the grandparent directory from the node command wrapper's path (~/.vite-plus/bin/node)
