docs: reflect 0.16.8-sqd.1 as npm latest (README matrix + versions.json dist-tag note)

0.16.8-sqd.1 is now the npm 'latest' dist-tag. Update the README Ponder-
versions matrix (add the 0.16.8 latest row; 0.16.7-sqd.1 is now published
but has no dist-tag; seam range → 0.15.17-0.16.8) and correct the
versions.json note, which #138 wrongly said 0.16.7-sqd.1 'keeps its
ponder-0.16.7 dist-tag' — no such tag exists (npm view dist-tags shows only
latest, ponder-0.16.6, ponder-0.15.17). 0.16.7-sqd.1 stays installable by
exact version; a ponder-0.16.7 tag would have to be added deliberately.
