feat(builder): SteamCMD first for Linux servers, and fall back to the next image

A draft built on a ready-made image whose files all live outside /server
(nodes keep only /server and /data) went round three times and ended as
WIP, although research had also verified the game's Steam app, which
SteamCMD installs straight into /server. The builder never tried it.

- research reads each Steam app's OS list. When it ships a Linux server,
  cm2network/steamcmd goes first in the variant's images and that variant
  is recommended. Windows-only servers keep images with Proton or Wine
  first. The research prompt says the same.
- build tries the variant's images in order: when no draft passes with one,
  the next image gets a fresh start. The first draft that boots wins; if
  none does, the PR gets the draft that got furthest, and its summary lists
  each image tried and how it went.

-- A game that tells players a second port (a reliable-messaging or query port it announces) needs it as
-  `{PUBLIC_PORT_<port>}` passed to the game's "external port" option, since nodes may publish it elsewhere.
 - Nodes always publish these container ports (only the host side moves when servers share a node).

-### Steam download cache

-Boot tests of Steam games (`installMethod: STEAMCMD`) start from a cached install, one Docker volume per
-app (`gbr-steamcache-<app id>`, label `gbr.cache=steam`), the same cache the AI builder uses. The
-cache is updated at most once a day; the node-agent's own install then only checks the files and
-fetches what changed. So Steam isn't asked for the whole game on every run, which keeps traffic from
-this machine's address low. The prune above keeps these volumes. To drop one game's cache:
-`docker volume rm gbr-steamcache-<app id>`; `STEAM_CACHE=off` turns the cache off.
