vp run fails to resolve node_modules/.bin executables with pnpm 12 on Windows (cannot find binary path)

まず vp run のタスク計画および実行可能ファイル解決のパスを確認し、次に pnpm 12.4.1 とドキュメントに記載された dev:serve スクリプトを使って Windows 11 のケースを再現します。node_modules/.bin/astro.cmd を介した astro の解決を pnpm 11 と比較します。vp run が実行可能ファイルを見つけ、pnpm 12 で両方の開発サーバーを起動できれば完了です。

vp run fails to resolve .bin executables with pnpm 12 on Windows (Failed to find executable astro)

Environment

• vite-plus: latest (reproduced on 0.1.24 and current latest)
• pnpm: 12.4.1 (reproduces), pnpm 11 (works)
• OS: Windows 11 Pro 10.0.26200
• Node: 24.20.0 (via mise)
• shell: PowerShell 7 / Git Bash

Summary

With the project installed by pnpm 12.4.1, vp run fails during task planning on
Windows even though the node_modules/.bin shims are well-formed and work fine
when invoked by pnpm itself.

Steps to reproduce

1. Windows 11, pnpm 12.4.1 (packageManager: pnpm@12.4.1, pnpm via mise, shamefullyHoist: true)
2. pnpm install
3. Root script:

   "dev:all": "pnpm --filter @sdata/web-vue run build:module && pnpm --filter @sdata/web-vue run jsongen && pnpm --filter @sd-design/sd-vue-docs run docs:vendor:only && vp run --parallel --filter @sdata/web-vue --filter @sd-design/sd-vue-docs dev:serve"
   

4. vp run dev:all (docs package dev:serve script is astro dev --host --force)

Actual result

error: Failed to plan tasks from `vp run --parallel --filter @sdata/web-vue --filter @sd-design/sd-vue-docs dev:serve` in task sd-design-vue-monorepo#dev:all
* Failed to find executable astro under cwd D:\work\sd-design\packages/sd-vue-docs with PATH: D:\work\sd-design\packages/sd-vue-docs\node_modules\.bin;D:\work\sd-design\node_modules\.bin;...
* cannot find binary path

The printed PATH starts with packages/sd-vue-docs/node_modules/.bin, which contains
the standard pnpm shims astro, astro.cmd, astro.ps1; astro.cmd's target
(node_modules/astro/bin/astro.mjs) exists.

Expected result

vp run resolves astro via astro.cmd (PATHEXT) like pnpm does, and starts the dev servers.

Key observation (pnpm 11 vs 12)

• With pnpm 12.4.1 installed node_modules: vp run fails as above.
• Rolling back to pnpm 11 and reinstalling: vp run works.
• pnpm --filter @sd-design/sd-vue-docs run dev:serve works under both pnpm 11 and 12,
  so pnpm 12's shims are functional; only vp's own executable resolution fails.
• Also reproduced with latest vite-plus after upgrading from 0.1.24 — not fixed upstream yet.
• Suspicious detail (may or may not be relevant): after the pnpm-11 reinstall, .bin
  contains duplicate-case entries (astro.cmd + astro.CMD, same for vite/rolldown/vue-tsc).
