// Package repository opens a typical on-disk Git repository and exposes its
// main stores and helpers.
//
// Start with [Open] when working with a bare repository root or a non-bare
// ".git" directory. [Repository] then provides access to ref storage, object
// storage, typed object fetching, commit queries, reachability helpers, and
// optional commit-graph access.
