test(e2e): include kiro in target matrix guards and multi-target install

The Local E2E Tests CI job failed because two matrix-coverage guards hardcoded the target set (claude, antigravity, cursor, cline, codex) and did not include the new kiro target. Add kiro (own-file, between cline and codex to match TARGETS order) to both guards, and add kiro to the multi-target install e2e so the target is actually exercised end-to-end.
