feat(scrolling-capture): scrollable long-screenshot pin sized to the … #138

	# Shift-left compile check: type-check the Windows-only solution on Linux using
	# EnableWindowsTargeting, so code written in cloud (Linux) sessions gets compiler
	# feedback without waiting for a Windows machine. This does NOT run tests or the
	# app — it only proves the managed code compiles.
	#
	# Proven: run #1 compiled the full solution (WinForms + WGC WinRT + FFmpeg.AutoGen)
	# on ubuntu-latest in ~78 s (restore 22 s + build 33 s), so this is enforcing.
