Docs still name the removed engine/example/pong-network #296

What is the type of issue?

Documentation is incorrect

What is the issue?

The engine's example/ folder is removed by NanoForge-dev/Engine#516 (its games move to the examples repository, demos/pong-network), but these docs still name engine/example/pong-network as if it were current:

• docs/specs/ecs.md line 180 (golden round-trips);
• docs/adr/0003-component-and-system-docs.md line 6;
• docs/rewrite-plan.md lines 181, 288, 1095, 1106;
• AGENTS.md line 130 (docs screenshots "taken on the engine's pong-network example") and line 188 ("The engine's pong-network example didn't").

The goldens and e2e now run on the test fixtures (packages/server-core/test/fixtures/game, plugins/scene/test/fixtures/breakout).

Where did you find it?

The docs review of #295.
