Replace the ASCII pipeline figure in README with two Mermaid diagrams —
the full pipeline (all 7 commands + 7 handover contracts) and agents per
phase — and add a "Primitives per step" decision-matrix to
docs/architecture.md, pointed to from README.
Corrects prior prose: /trekexecute spawns no sub-agents; Phase 5 swarm is
6 fixed + 2 conditional; cross-cutting = 7 hook scripts incl. Stop->OTEL.
Both diagrams validated with mermaid-cli 11.12.0 (render clean);
node --test 756/0 fail (doc-consistency pins intact).
