Add CTR-013 to the compiler threat detection specification to cover the argument injection defense already implemented in the compiler. Package and container image names starting with '-' are rejected at compile time before being passed to exec.Command calls (npm/npx, pip/uv, Docker), preventing hyphen-prefix names from being interpreted as CLI flags. - Add CTR-013 rule to Section 4.1 core rule catalog - Add T-CTR-013 test ID to Section 7.1 test catalog - Add CTR-013 row to Section 6.1 implementation mapping table - Bump version to 1.0.3 and update change log Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

CTR-013 – Argument Injection via Package/Image Names: Package names (npm/npx, pip/uv) and container image names starting with
-are passed directly toexec.Commandcalls. A name like--privilegedor-exploitwould be interpreted as a CLI flag rather than a package/image name, enabling argument injection.Coverage Status
