[Bug][Core] OpenClaw runtime fails to start on Windows (Path not found), causing Controller WS loop

[shangxinyu1]

Environment

Platform: Windows
Version: 0.1.12-nightly.20260416
Component: OpenClaw Runtime / Controller Orchestrator

Steps to Reproduce

1. Launch Nexu Desktop on Windows.
2. Open the nexu local cold-start control room dashboard.
3. Observe the status of the OpenClaw and Controller components.

Actual Behavior

• The OpenClaw component remains in a STOPPED state.
• The Controller is RUNNING (e.g., bound to port 50800), but is completely non-functional. It is stuck in an infinite loop: openclaw_ws_connecting -> openclaw_ws_error.
• The Controller stderr outputs garbled text: ϵͳÕҲ»µ½Ö¸¶¨µÄ·¾¶, which is GBK encoding for "系统找不到指定的路径" (The system cannot find the path specified).
• openclaw-2026-04-16.log shows: WARNING: could not find openclaw global installation, symlink not created.

Expected Behavior

• The orchestrator should correctly resolve the executable paths for the OpenClaw runtime unit on Windows (handling \\ vs / and spaces in paths correctly).
• If OpenClaw fails to start, the Controller should not silently hang in a WS loop, but rather surface a clear "Engine missing/failed to start" error to the frontend UI.

Impact

Severity: P0 (Critical)

• Core engine fails to start on Windows.
• Completely blocks users from using the agent.
• Garbled GBK logs make debugging extremely difficult for average users.

Root Cause Speculation

1. Path Resolution Bug on Windows: The spawn/exec command for OpenClaw in the orchestrator is likely passing an invalid path (e.g., missing quotes around C:\Users\Amy\AppData\Local\Programs\... or incorrect binary extension like missing .exe or .cmd).
2. Antivirus/Defender Isolation: Windows Defender might have quarantined the OpenClaw binary during the nightly update.
3. Missing Symlink Logic: The script relies on a global symlink that fails to create on Windows due to strict permission requirements (requires Admin for symlinks on older Windows versions).
