OpenWinSidecar 0.1.1

Three winget-validation failures taught us what a clean, silent, GPU-less machine does to an
installer built on one dev box. This release makes the Windows installer survive all of it.

Fixed

• Ghost virtual monitors eliminated. devcon install unconditionally creates a new
  device node, so reinstalls stacked up ROOT\DISPLAY\0001, 0002, … (Settings showed extra
  gray display tiles). Node creation now runs only when no virtual display exists, and
  uninstall removes all instances + the DriverStore package (previously only 0000).
• Silent installs never hang. Two headless-VM hang sources removed: the FFmpeg-missing
  MsgBox (silent installs now log; interactive keeps the prompt) and the driver operations
  themselves — in silent installs pnputil staging and devcon node creation run
  fire-and-forget, so setup terminates even where an IddCx driver can never start.
  Verified: silent install wall time 12.3 s, virtual display appears ~2 s later.
• FFmpeg made a real dependency. The installer detects FFmpeg like the runtime and
  installs Gyan.FFmpeg via winget when missing (interactive); winget installs declare it
  as a package dependency. No FFmpeg at all still works — the app degrades to JPEG and
  tells you exactly what to install.

Added

• One-click FFmpeg fix in the dashboard: if FFmpeg is missing, the app shows a warning
  banner with an Install FFmpeg button (background winget install, auto re-resolve — no
  restart needed).

Notes

• The installer is not code-signed; the release notes carry the SHA-256 to verify your
  download. winget install --id julianmb.OpenWinSidecar is pending Microsoft review.
