GitHub Releases-backed snapshot artifact store.
Runtime fetching resolves immutable snapshot and history releases via the
GitHub Releases API and downloads public assets via Req. Publishing is
handled with the gh CLI, intended for local maintainer workflows and
GitHub Actions.
This shared transport is internal. Runtime consumers configure snapshot
sources through LLMDB.load/1; maintainers use the supported
mix llm_db.snapshot.* and mix llm_db.history.* tasks. Direct publishing
calls are documentation-deprecated through the current major release.
