fix(kimi-code): select compatible PowerShell for Computer Use

[wbxl2000]

Related Issue

No linked issue. This fixes Windows installation failures reproduced from Kimi Computer Use debug sessions and a naming mismatch observed after installation.

Problem

The Windows Kimi Computer Use installer was always launched with the system powershell.exe. On systems where that PowerShell installation does not provide commands required by the official setup script, such as Get-FileHash, installation fails even when a compatible PowerShell 7 installation is available.

The failure also happened after entering the capability installation flow, without first checking whether the selected PowerShell could run the official installer.

A runtime repair also replaced the plugin even when its wiring was already healthy. On Windows, a live plugin MCP process can keep that managed directory locked, exposing a raw EBUSY rename error instead of actionable recovery guidance.

Before installation, the Official marketplace used the built-in capability name Kimi Computer Use. After installation, the Installed tab used the Windows plugin manifest name Kimi Computer Use for Windows, making the same product appear to change names.

What changed

• Probe the system Windows PowerShell for the version and commands required by the official installer.
• Fall back to PowerShell 7 from its trusted Program Files installation path when the system PowerShell is incompatible.
• Fail with path-specific diagnostics before downloading the installer or changing plugin wiring when neither installation is compatible.
• Continue to run the unchanged official setup script, while forcing UTF-8 console output so PowerShell diagnostics remain readable.
• Keep healthy plugin wiring untouched when only the Windows runtime needs repair.
• Explain that Kimi Code must be restarted when live plugin files are locked, including after removing a built-in capability plugin.
• Use Kimi Computer Use for Windows for the Windows capability so the Official and Installed tabs display the same name.
• Cover the PowerShell selection, fail-before-mutation, healthy-plugin, locked-file, removal-hint, and Windows display-name paths with focused tests.
• Add a patch changeset for @moonshot-ai/kimi-code.
