Close the desktop store item, and fix a check that had started lying

MORE_STORES item 2 is done: stores/warp-engine-desktop-store and
stores/ttg-desktop-store. The write-up records what the implementation changed
about the plan — chiefly that the `html` asset is not a downloadable archive but a
hosted directory, so a browser title becomes a menu entry that opens its page
rather than an offline install.

Separately: `check-repos.sh` reported `infra/wiki-pages` as STALE while the repo
was plainly there. Gitea caps a page at 50 items whatever `--limit` says, so
`tea repo list --limit 1000` had been quietly returning the first 50 — invisible
until today, when the estate reached 51 repos. The check now pages through, and
fails loudly if the server returns nothing at all rather than declaring the whole
workspace stale.
