  1. fix: validate split short-option values 

    <!-- agent -->

Single-character keyword arguments are transformed into an option token and
a separate value token. The unsafe-option candidate builder only checked the
keyword name, allowing an option-like value to bypass guards shared by clone,
remote, revision, blame, and archive operations.

Include dash-prefixed values only when short options are actually split,
including sequence values, while preserving bare values and the non-splitting
compatibility path.

Git baseline a23bace9 defines clone -n and --upload-pack as distinct options,
matching the argv boundary this validation now preserves.

Refs GHSA-r9mr-m37c-5fr3.

  2. fix: reject unsafe clone templates 

    <!-- agent -->

Treat git clone --template as unsafe because caller-controlled
templates can install hooks that execute during clone.

Add regression coverage for both direct option and keyword forms.

  3. fix: guard diff output options 

    <!-- agent -->

Reject unsafe diff options before revision parsing or Git invocation so
callers cannot write command output to arbitrary filesystem paths.

Cover commit and index diffs, including option-like revisions, and
preserve an explicit allow_unsafe_options escape hatch.
