Mirror the approved S-00 split into the backlog: replace the single S-00
slice with sub-slices S-00-a (BFF + health), S-00-b (Docker + compose +
smoke), S-00-c (Gitea Actions CI), S-00-d (contributor workflow), and
S-00-e (docs scaffold). Gitea remains the system of record; the issues
are managed with the tea CLI.
