fix(windows): use proper argument splatting for Claude CLI execution

The previous approach using:
  & claude $ClaudeArgs

was not properly expanding the array, causing Claude CLI to see:
  error: unknown option '--settings C:\Users\kaidu\.ccs\sonnet.settings.json'

Fixed by using direct splatting:
  & claude --settings $SettingsPath @RemainingArgs

This ensures proper argument quoting and separation, matching bash behavior:
  exec claude --settings "$SETTINGS_PATH" "$@"
