- Use PowerShell to inspect node.exe command lines on Windows,
since tasklist output does not include them.
- Also check for dedicated openclaw.exe/clawd.exe processes.
- Skip the interactive prompt in non-interactive sessions so the
preview-only behavior is preserved.
- Update tests accordingly.
Relates to #7907

OpenClaw processes (via pgrep/tasklist) before hermes claw migrate.
Warns the user that messaging platforms only allow one active session

Fixes#7907
