- build_zip.sh: derive <repo>-all.zip name from $GITHUB_REPOSITORY when
set (in Gitea Actions the toplevel basename is the worker dir, not
the repo). Falls back to git toplevel for local invocations.
- release.yml: skip assets above MAX_BYTES (200 MiB Gitea ceiling) and
continue on individual upload failures. Job only fails if ZERO assets
uploaded. Previously one oversized zip would block the whole release.
