scripts/web-app-accept.sh: 14 checks, network-free — temp git remote from
the framework dir, file:// substituted into a temp app copy, then fetch +
wo.lock + build; 401-without-token; empty list; 201 create; 409 duplicate
(@unique); 400 malformed json; list/show payloads; 404; 201 order (FK); 409
delete-while-referenced with the server surviving; pipelined keep-alive (2
responses, 1 connection); SIGTERM; WAL restart persistence. Wired as
`just web-app`. 14/0.
