Detailed Description

Live UI-input recorder. Install one instance in EditorShell when the user passes --save-repro <path>; call snapshotFrame() once per editor frame (before any UI widgets have consumed input events.

• right after window_.beginFrame() / ImGui::NewFrame()). On process exit, call flush() to serialize the recording to the destination path.

The recorder captures raw ImGui input state (mouse position, mouse button mask, modifier state, wheel deltas, discrete key/char events) plus enough metadata to re-instantiate the editor session. That's the input boundary BELOW menu / tool / compositor dispatch, so a replay exercises every stage of the stack: a recording of a bug you can see in the editor always reproduces that bug in playback, regardless of which layer owns it.
