Mirror the 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). Source of truth remains Gitea; #1 is closed by
tools/split-s00.sh with a comment pointing at the replacements.
