Adds tests/run-atlas-determinism — imports generate_atlas as a module
and calls process_body() twice with seed=42 and dry_run=True, comparing
the returned markers dicts as JSON. No wiki files are written.
Guardrail against determinism regressions in terrain analysis, city
placement, A* road routing, infrastructure MST, and gate terminal
placement. GJ892f (domed, population 300, 1 city) is the smallest
well-exercised case.
Makefile target: make test-atlas-determinism.
Wired into tests/run-all alongside run-ipc-integration and run-visual.
