process-detector: ps command and path splitting broken on Windows

[blueberrycongee]

Problem

electron/process-detector.ts has two Unix-only assumptions that make the entire module non-functional on Windows:

1. ps command does not exist on Windows (line 119)

execFile("ps", ["-eo", "pid,ppid,args"], (err, stdout) => { ... })

ps -eo pid,ppid,args is a Unix command. On Windows this throws ENOENT. The entire detectCli() function fails immediately.

2. Path splitting only handles forward slashes (line 26)

const baseName = firstToken.split("/").pop() ?? "";

Windows paths like C:\Program Files\nodejs\node.exe are not split on \, so baseName retains the full path string. This causes wrapper detection (WRAPPER_NAMES.has(baseName)) and CLI pattern matching to fail.

Windows alternatives for process enumeration

• Get-CimInstance Win32_Process | Select ProcessId,ParentProcessId,CommandLine — exposes all three required fields (PID, PPID, CommandLine)
• tasklist /fo csv /v — available by default but lacks ParentProcessId and full CommandLine
• wmic process get ProcessId,ParentProcessId,CommandLine /format:csv — deprecated, removed from newer Windows

Affected functionality

• CLI tool detection (claude, codex, etc.) in terminal tabs
• Process tree traversal for session tracking
