Initial public release. Forked from Stengo/DeskPad (MIT-licensed) and extended into a Swift Package with the following capabilities:

VirtualDisplay — create and manage virtual displays via the private CGVirtualDisplay API
VirtualDisplayConfiguration — configurable resolution, refresh rate, HiDPI support, vendor/product identifiers, and preset configurations (.preset1080p, .preset4K, .presetSignage)
DisplayStreamRenderer — CGDisplayStream-based frame delivery with both IOSurface and CVPixelBuffer output paths
DisplayRecorder — record virtual display content to H.264/HEVC MP4/MOV via AVAssetWriter, with .standard, .highQuality, and .hevcHighEfficiency presets
FrameOutputStream — emit encoded H.264/HEVC Annex-B or raw CVPixelBuffer frames for RTMP streaming, OBS integration, or custom pipelines, via VTCompressionSession; presets for .rtmpStreaming, .highQuality, .realtime
VirtualDisplayController — high-level facade combining display, recording, and streaming
VirtualDisplayView (SwiftUI) and VirtualDisplayNSView (AppKit) for preview integration
