jensandClaude Sonnet 5 44bbd00336 Fetch games into a volume at runtime instead of baking them into the image

927MB of the image was just t7g's two CD ISOs, which can't be meaningfully
compressed (already-compressed FMV/audio). Move the smbget/unzip step out
of the Dockerfile and into scripts/fetch_games.sh, run from server.sh on
container start: it populates GAMES_HOME on first run and skips the fetch
if games are already present. run.sh mounts a named volume so the games
survive --rm restarts instead of being re-downloaded every time. Image
drops from 1.6GB to ~690MB; first container start now needs network access
to the vlda-01 SMB share to seed the volume.

TODO

~~~Reduce image size of jayfield/dosbox-novnc (currently ~~2.3GB).~~~~ Done in two steps:
1. Merged the game download/extract steps and the unzip/smbclient install into a single layer (so the downloaded zips and the packages only needed to extract them no longer persist in the final image). 2.31GB -> 1.6GB.
2. Stopped baking the games into the image at all (927MB of that was just t7g's two CD ISOs). scripts/fetch_games.sh now downloads them from the SMB share into ${GAMES_HOME} (/opt/games) on first container start instead, skipping the fetch if already present. run.sh mounts a named volume (dosbox-games) so the games persist across --rm restarts. 1.6GB -> ~690MB. Container now needs network access to vlda-01 at runtime (not just build time) for the first start.
