Problem: After Effects 26.3 copies the current composition frame to the
system clipboard; EffectCraft could only write it to a file (Save Frame As).
Fix: new command comp.copyFrame {comp?, time?, scale?} renders the frame as
Save Frame As ▸ File does and emits Event::CopyImage (pixels not
serialized); the egui frontend puts it on the clipboard after checking the
buffer size. In the Composition menu (translated) and the viewer's context
menu; drivable by id over the control channel / MCP.

The EXR sequence writer and comp.saveFrameAsExr clamped colour to 0..1 before the sRGB decode, so a 32 bpc project lost every over-range value. The lower bound stays at 0 and alpha stays clamped. Tests cover Rgba and Rgb sequences and saveFrameAsExr.
