//! Git plumbing: keep a bare mirror fresh and serve `upload-pack` from it.
//!
//! All git work is delegated to the system `git` binary, so protocol
//! correctness - including protocol v2, shallow and partial (filtered) clones -
//! comes for free. The proxy never reimplements the wire format; it only:
//! correctness - protocol v2, shallow and partial (filtered) clones - comes from
//! `git` itself, not a reimplemented wire format. (Partial clone additionally
//! needs `uploadpack.allowFilter`, which the serve path sets; see `local_cmd`.)
//! The proxy only:
//! 1. maps a request to a bare mirror under the cache root,
//! 2. runs an incremental `git fetch` from upstream (coalesced per repo),
//! 3. streams `git upload-pack` output from the local mirror to the client.
