Message:
Center code-execution text output, demo a GIF saved from code UnicodePlots (and any other code block's plain stdout) now centers the same way image-based plots already do via their own PadLeft, instead of hugging the left edge while GR/CairoMakie output sits in the middle. Also adds a Julia example that saves an animated GIF from a ctrl+e block -- confirms the existing GIF cache path (Fase 7) already applies to execution-produced images too, no code change needed there.

+### An animated GIF from code
+
+A saved `.gif` is displayed the same way any other executed-code image
+is -- and if it has more than one frame, it plays back in a loop just
+like a `.gif` referenced directly in markdown.
+
+```julia
+using Plots
+gr()
+anim = @animate for i in 1:40
+    plot(1:100, x -> sin(x / 10 + i / 4), ylim=(-1.2, 1.2), legend=false)
+end
+gif(anim, "wave.gif", fps=20)
+```
