harn eval prompt <file> --fleet <models> — render and optionally run
a single .harn.prompt template across a fleet of models so authors
can validate the capability-adapted envelope per model side-by-side.
Render mode is the v1 acceptance path: it pushes an LLM render
context per model, calls the template engine, and emits the rendered
envelope plus a wire-format diff. Run and judge modes synthesize a
tiny Harn driver and route through the existing execute_run
pipeline so credentialed LLM calls, mock fixtures, and the
LlmRenderContext injection all stay on the canonical path.
