New additive targets, the existing server/exporter/smoke-client/enet-test
targets are byte-for-byte unchanged (make verify-phase6 re-run clean
after this, see previous commit):
- supervisor-build: builds server/cmd/game-server-supervisor with a
pinned golang:1.23-alpine (matching go.mod's go 1.23)
- game-server: the same dedicated-server export as `server`, plus the
supervisor binary, with the supervisor as ENTRYPOINT instead of the
direct launcher script -- this is what makes the process-ready/
assignment-ready control-plane registration from the last two
commits actually reachable in a real deployment.
Verified with a real docker build --target game-server, not just by
reading the file: both binaries land at the expected paths with
correct permissions, and the supervisor prints its usage text when
run directly.
deploy/k8s/base/fleet.yaml does not reference this image or invoke the
supervisor's flags yet -- documented inline and in
multiplayer-next.md; that's the next concrete step, not attempted here
since the exact flag values (control-plane URL, workload-token mount
path) are deployment-environment decisions this sandbox can't make.
