vp run ignores cd before a nested vpr in a script and runs the parent package's task #3129

Describe the bug

If a package.json script does cd <dir> && vpr <task>, vp run ignores the cd. It looks up <task> in the package it started from instead of the one in <dir>. Putting the same command in a subshell, (cd <dir> && vpr <task>), gives the right result.

The log shows vp run running the nested vpr itself rather than handing the whole line to the shell. For plain it prints $ echo ROOT, which is the root's hello.

This happens without any pnpm workspace. The repro has no pnpm-workspace.yaml and no lockfile, so it's a different bug from #3013, though the symptom is the same: vpr in a subfolder runs the root's task.

Reproduction

mkdir repro && cd repro && mkdir ui
echo '{"name":"root","private":true,"scripts":{"hello":"echo ROOT","plain":"cd ui && vpr hello","sub":"(cd ui && vpr hello)"}}' > package.json
echo '{"name":"ui","private":true,"scripts":{"hello":"echo UI"}}' > ui/package.json

vpr plain   # prints ROOT, expected UI
vpr sub     # prints UI
(cd ui && vpr hello)   # from the shell: prints UI

Output:

$ vpr plain
$ echo ROOT ⊘ cache disabled
ROOT

$ vpr sub
$ (cd ui && vpr hello) ⊘ cache disabled
$ echo UI ⊘ cache disabled
UI

Expected

cd ui && vpr hello should run ui's hello, the same as it does in a shell or under npm run. If vp run handles a nested vpr itself, it should apply any earlier cd in the same command before it resolves the task.

Environment

• vp v1.1.0 (global, no local vite-plus)
• Node v24.19.0
• Linux
