Subject: [PATCH] Add legacy_tool.dot workflow and CLI tests for backwards
 compat
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Exercises the old tool_command attribute through validate and
dry-run to catch regressions in the tool → script compatibility.
