chore(examples): drop PNG thumbnails, ship WebP only (-80% asset size)

The PNG fallbacks were carrying 80% of the gallery's bundled weight
(16 MB of 20 MB) and serving virtually no traffic — WebP is supported
on ~97% of in-use browsers, and the few hold-outs (very old Safari)
fall through to the CircuitPreview SVG mock via the existing onError
handler. No visual regression for modern browsers.

Numbers:
- before: 258 files, ~20 MB total
- after:  129 files, ~3.6 MB total (avg 28.6 KB / WebP)

ExampleThumbnail simplified: drops the <picture>/<source> wrap around
the WebP <source> + PNG fallback, just renders the WebP <img> directly
with onError → CircuitPreview.
