add inline notation, and take the tilde back from strikethrough

~sub~, ^sup^, ==mark==, and ~~strike~~ moved in from goldmark. Not a
preference: goldmark's strikethrough claims a single tilde as well as a double,
so with it enabled H~2~O rendered as H<del>2</del>O — measured before the
change. Two features cannot share a byte and both be correct, so notation owns
it and the authored syntax stays exactly as ADR-0058 documented.

The second failure was worse and only showed up under test. Under delimiter
rules `x^2 + y^2 = z^2` pairs its carets across the whole expression and renders
x<sup>2 + y</sup>2 — prose silently becoming markup, in exactly the content this
engine is for. So a single run is scanned rather than paired, and may not cross
whitespace: a subscript holds a formula, never a phrase. Pandoc draws the same
line. The cost is that a single run takes its content literally, so there is no
emphasis inside a subscript, which the ADR states rather than leaving to be
discovered.

New package under internal/ext, which is a stop condition and was asked. It
takes the extensions counter to 4, past its threshold, and the answer is still
no: four features attach in three unrelated ways, and two goldmark extenders
compose in goldmark's own extender list, which is already the registry for that
shape.

The example site's hand-copied extender list drifted, exactly as the latent row
added last loop predicted — the demo case failed and named it. Both are now in
step again.
