ICM Grill

Interview like grill-with-docs. Emit one of six fleet trees. ICMTemp is a designer, not a product catalog. Do not wrap RinDig icm-architect and hope: its five generic questions are the wrong interviewer.

Load references/trees.md and references/domain-model.md before opening Round 1 so the terminology rules shape the grill. Load references/walk-test.md only at confirm / emit.
