- Collection round-trip through a second collection, validating both canvas resolutions, item routing, and transforms. - Resize rejection during recording, unchanged state/geometry, no loading transition, and successful retry afterward. - Rapid separate width/height updates, validating both promises resolve into one coherent resize without loading.
Attempt to switch to a collection with different base resolutions while recording. The switch should reject before removing the current scene graph.

Motivation
Auto Optimizer gives creators safe stream settings without requiring them to understand canvas, frame-rate, bitrate, or encoder tradeoffs. It validates the selected streaming configuration against the user's hardware and upload connection, reducing the risk of overload and dropped frames, especially with Dual Output and Twitch Enhanced Broadcasting.
Context
This is the Desktop side of the coordinated Auto Optimizer update in OSN. OSN performs native bandwidth and hardware measurements, while Desktop owns destination routing, temporary YouTube resources, result validation, UI state, and applying recommendations.
Active bandwidth testing currently supports Twitch and YouTube. Twitch Enhanced Broadcasting remains Twitch-managed, and 10-bit video (HDR) configurations bypass optimization.
Canvas promotion depends on the relative-coordinate scene collection changes included in this branch, allowing canvas resolutions to change without altering the visual scene layout.
