Architecture diagrams generated by gsd-phase-researcher now enforce
data-flow style (conceptual components with arrows) instead of
file-listing style. The directive is language-agnostic and applies
to all project types.
Changes:
- agents/gsd-phase-researcher.md: add System Architecture Diagram
subsection in Architecture Patterns output template
- get-shit-done/templates/research.md: add matching directive in
both architecture_patterns template sections
- tests/phase-researcher-flow-diagram.test.cjs: 8 tests validating
directive presence, content, and ordering in agent and template
Closes#2139
