b4 ships editor helpers (Vim/Emacs syntax highlighting for the `b4
review` reply editor) and an `agent-reviewer.md` prompt under `misc/` in
its source tree, but these files are absent from the PyPI sdist the
package is built from. Fetch the matching git tag and expose it as
`passthru.src-misc` so downstream consumers (starting with the
`b4-review-vim` plugin) can reuse it instead of each fetching the
repository themselves. Pinning `rev` to `v${version}` keeps it in sync
with the packaged version.
