//! Credential resolution for git-lfs.
//!
//! Bridges to git's credential machinery (`git credential fill/approve/reject`)
//! and adds a small in-memory cache so repeated requests against the same
//! host don't re-shell-out for every batch / upload / download.
//!
//! # Scope (v0)
//!
//! - [`Query`] is the (protocol, host, path) tuple git's credential helpers
//! key on.
//! - [`Credentials`] holds a username + password.
//! - [`Helper`] is the trait the API client calls into when it gets a 401.
//! - [`GitCredentialHelper`] shells out to `git credential` for the real
//! resolution.
//! - [`CachingHelper`] memoizes the answer in-process.
//! - [`HelperChain`] tries each helper in order and writes
//! approve/reject decisions back to all of them.
//!
//! Deferred (see `NOTES.md`): netrc, askpass, NTLM/Kerberos, multi-stage
//! `wwwauth[]`/`state[]`, URL-pattern config (`credential.<url>.helper`).
