Every reviewer flagged that runAgent appended llm.Text(input) unconditionally, so
an image-only run (blank prompt) emitted an empty TextPart — inconsistent with the
sibling runSession.AttachImages which guards it. Mirror that guard
(strings.TrimSpace(input) != ""). Also:
- copy opts before appending (variadic backing array can have spare capacity; avoid
aliasing a caller's slice).
- reword the doc comment to drop the mort-agentexec reference (executus is a
standalone lib; a consumer name doesn't belong in its godoc).
Tests: image+text are co-located in ONE user message; an image-only run emits no
blank TextPart.

The executor passed only the text `input` to majordomo's agent.Run, silently
dropping inv.Images — so a multimodal run (vision: chatbot @mention, chat API)
lost its images on the executus path. majordomo's Run input arg is text-only, so
fold the images into the first user message (text + image parts) via WithHistory
and call Run with empty input, mirroring mort agentexec's multimodal seeding. The
image-less path is unchanged (prompt passes straight through).
Tests: a run with Images carries the image bytes + prompt into the first model
request; the text-only path still reaches the model.
