0.3.3

Fixed

• The laptop brightness key now reaches Plith. It never had. The WMI namespace was written
  one backslash short, \.\root\wmi instead of \\.\root\wmi, and ManagementScope rejects
  that from its constructor before WMI is contacted, so the subscription to
  WmiMonitorBrightnessEvent failed on every machine Plith has ever run on. A brightness key is
  consumed in the driver stack and there is no key to hook, so that event was the only way Plith
  could see one: pressing it dimmed the screen and Plith showed nothing. Brightness hotkeys set
  in Settings were never affected and always worked, which is why this looked like a missing
  feature rather than a defect.
• The same failure can no longer hide. It was reported at INFO as "No brightness event
  source", which is what a desktop with no internal panel was expected to say, so a broken path
  and a normal machine produced the same line. Measured on a desktop with no internal panel and
  no WmiMonitorBrightness instance: subscribing succeeds there too and simply never fires.
  Reaching that branch therefore always means a defect, and it now logs at WARN and says so.

Added

• The first brightness event of a session is logged, so whether this feature ever heard anything
  on a given machine can be answered from the log instead of from the screen.
