/**
 * Read-only git toolset (N4.4) — types.
 *
 * A reviewing agent needs git constantly: what changed, who wrote it, what the
 * merge base was. Handing it a shell to run `git` in is the wrong shape twice
 * over — it can then run anything, and git itself has write-capable options
 * (`--output=<file>`, `diff.external`) that a free-form argument string would
 * carry straight through.
 *
 * So these tools are BOUNDED: the model supplies validated values (a ref, a
 * path, a line range), never flags, and each tool assembles a fixed argv from
 * them. The whole surface is six read-only subcommands. Execution goes through
 * the same hardened runner as {@link BackgroundCommandPolicy} — argv arrays,
 * no shell, a cwd sandboxed to the repository, a timeout, a byte cap — and the
 * full output is banked, so a 40 MB diff costs a bounded preview plus a
 * pointer.
 *
 * Naming: nothing else in the types folder claims `Git`, and `tools.ts` owns
 * the unprefixed `Tool*` names, so these carry the `GitTool` prefix
 * (Critical Rule 9).
