Status: implemented on `main`

## Goal

Expose the flexible layer graph through production code while preserving the
service maintainability budget.

## What Landed

  `research/knowledge-hub/knowledge_hub/layer_graph_support.py`
- new runtime-surface support module:
  `research/knowledge-hub/knowledge_hub/topic_runtime_surface_support.py`
- new CLI command: `layer-graph`
- topic-scoped `layer_graph.generated.json` / `layer_graph.generated.md`
  artifacts

## Outcome

Phase `113` is complete.
