Capture the diagnostic notes for the issue we hit after every
`dev-deploy.yaml` redispatch: the freshly-bootstrapped "Dev Sandbox"
game ends up `cancelled` ~15 minutes later, with the runtime
reconciler reporting "container disappeared". The engine never
shows up in `docker ps -a --filter label=galaxy-game-engine`, so
either it never spawned or it was removed before any host-side
snapshot.
`KNOWN-ISSUES.md` records the symptom, the log excerpt, three
working hypotheses (runtime spawn race, `--remove-orphans`
interaction, engine `--rm` lifecycle), and the investigation
checklist before opening an issue. The README gets a one-line
pointer so future redeploys land on the doc immediately.
No code change — this is the placeholder so the next person
investigating the cancellation pattern does not have to
rediscover the diagnostic from scratch.
