Upgrade from the card, behind a three-dot menu

An installed title's version line now reads `0.1 → 0.3` where the catalog has moved on,
so a card answers both questions somebody brings to it: what is installed, and is there
anything better. Which version is installed was already recorded — `state.json` has
always carried it — what was missing was anywhere to act on it.

The card leads with Play (or Open, for a hosted title) and puts the rest behind a ⋮
button: Upgrade, which fetches whatever the catalog now has, and Uninstall. Upgrade stays
visible while disabled rather than appearing and disappearing — a menu whose items come
and go makes a person hunt for the one they used last time, and greyed out already says
"not now". Playing stays the headline even with an upgrade waiting: the build on the disk
still runs, and wanting to play it is not the same as wanting to wait for a download.

The menu is a `<details>`, so its open state is the DOM's and the keyboard needs no
teaching. Closing it on an outside click is the grid's job, not a card's: cards are
rebuilt on every render, so a listener per card would be a listener per render.

Package names lose their spaces — `WarpEngineClient-2.3.0-arm64.dmg` — because a space in
a release asset is a space in every curl, script and shell command that touches it. Set
per target rather than globally: nsis and portable would otherwise resolve to the same
.exe name and overwrite each other. `productName` is untouched, so the app is still
called WarpEngine Client where a person sees it — in the Dock and in /Applications.

Tested on a sandbox store by rewriting one state record to claim an older build, which is
what the engine actually compares: the window then offered `Upgrade:on` for that title and
`Upgrade:off` for the current one, and pressing it took the record from 0.1 to 0.2 with
the old payload removed first. The self-test asserts that pairing on every installed card,
because a closed menu photographs identically whether or not its items are right.

In Hungarian the catalog refresh and the new Upgrade both wanted "Frissítés"; the refresh
is an icon with a tooltip, and a tooltip can afford to say *Katalógus frissítése*.
