fix(docs): serve README images via jsDelivr (raw.githubusercontent 503s)

[cobusgreyling]

Summary

• GitHub’s raw.githubusercontent.com CDN is intermittently returning 503 for every image under assets/visuals/, so the README and showcase show broken images even though the files are fine in git.
• Point README, showcase (docs/index.html), and star-history page image URLs at jsDelivr (cdn.jsdelivr.net/gh/...@main/...), which consistently returns 200 for the same files.
• After automated star-history SVG updates, purge jsDelivr cache so the chart does not stay stale.

Test plan

• curl all README asset URLs on jsDelivr → 200
• Same URLs on raw.githubusercontent.com → 503 (reproduces outage)
• After merge: hard-refresh https://github.com/cobusgreyling/loop-engineering and confirm logo, LE5 hero, demo GIF, primitives, loop-cycle, patterns, star-history load
