feat(screens): phase 9 — real screenshots, from a real shard

D4 asked for screenshots of the review stack rather than placeholders. Seventeen
of them: eleven of the site in a browser, six of the app on a phone, all from one
demo deployment wired to a running ServUO shard over a real sidecar, captured on
one day (D42).

The deployment is branded "Runic Gateway Demo" rather than a real community (D43),
and the captures sit beside the claims they support — the homepage, /features/, and
five of the administration pages phase 7 could describe but not show (D44).

The rig is committed rather than remembered (D45):

  scripts/seedDemo.mjs        content, by driving the site's own API — never SQL,
                              because a row the product could not have produced is
                              a screenshot of a product that does not exist
  src/data/screens.mjs        every capture: route, viewport, scroll, alt, caption
  scripts/captureScreens.mjs  npm run screens:capture
  scripts/checkScreens.mjs    the ninth check script, in CI

Shard-side dressing is servuo-plugins' scaffolding (D46), never deployed.

The rig found five things nothing else had. One is fixed upstream — a fresh
module-uo install pinned wire protocol 3 against a sidecar speaking 4, released as
v1.0.2, which this repo's own facts check then caught in platform.json. Four are
raised as product observations and worked around in the rig: a renamed guild
member never reaches the site, a guild deleted while the shard is down is a ghost
row forever, "Houses in danger" cannot show a house that was already collapsing,
and the app's news list prints raw ISO timestamps.

Players online reads 0. Logging a character in needs a UO client driven by hand,
and that is where this stopped — PLAN.md §10 says exactly why, and how to retake
the two frames that would change.
