Regression in v1.4.10: git-based plugins fail with "No git binary found in $PATH" on Windows CLI

[Vafl9]

Description

After upgrading from v1.4.9 to v1.4.10, git-based plugins fail to install/update on Windows CLI with the error:
ERROR service=plugin pkg=superpowers version=git+https://github.com/obra/superpowers.git error=No git binary found in $PATH failed to install plugin

Environment

• OS: Windows 11 Pro
• OpenCode CLI version: v1.4.10 (installed via npm install -g opencode-ai)
• OpenCode Desktop version: v1.4.10 (works fine)
• git: v2.51.2.windows.1, installed at C:\Program Files\Git\cmd\git.exe
• Binary path: C:\Users\<user>\AppData\Roaming\npm\node_modules\opencode-ai\node_modules\opencode-windows-x64\bin\opencode.exe

Expected Behavior
Plugin installs/updates successfully, as it does in v1.4.9 and in OpenCode Desktop v1.4.10.
Actual Behavior
Plugin fails to install. The which.sync('git') call inside @npmcli/git (used by @npmcli/arborist for git-based package resolution) cannot find git in PATH, despite git being available in the system PATH.

Key Observations

• v1.4.9 CLI: Works correctly
• v1.4.10 CLI: Broken
• v1.4.10 Desktop: Works correctly (same machine, same version)
• git is accessible from terminal: where.exe git returns C:\Program Files\Git\cmd\git.exe

Workaround
Downgrade to v1.4.9
