local-model bed: prove model-access answered by a node (ADR 0055)

A single-node VM bed: an ollama provider and a local-model consumer are assigned; the resolver answers the consumer's model-access with the local node (no licence demanded), the consumer's openai.env is templated with the served endpoint, and a request to it reaches the running model server. Proves the node-answer of model-access end to end (ollama on host network, keyless). Claude-Session: https://claude.ai/code/session_01LrgweAeERJYBg88c5cKDzF

+# One machine that becomes a mesh, then proves model-access answered by a NODE (novox/hq ADR 0055):
+# a local model server (Ollama) on the node ANSWERS the model-access provision, and a consumer that
+# requires model-access is handed the server's ENDPOINT — base URL + model — instead of a vendor
+# credential. No licence, no key: the consumer points an OpenAI-compatible client at the mesh's own
+# model.
+#
+# The flow the test drives:
+#   the ollama provider is assigned (it `provides: [model-access]` at node scope, `serves` its port and
+#   model)  ->  the local-model consumer requires model-access and is answered by the local node  ->
+#   the mesh fills the consumer's bound facts with ollama's at/port/model  ->  the consumer's templated
+#   openai.env carries OPENAI_BASE_URL=http://<at>:<port>/v1. The test asserts that URL and that a
+#   request to it reaches the running model server.
+#
+#   MESH_LAB_HOST_BINARY=.../mesh-host   MESH_LAB_BUNDLE=.../examples/substrate-first-node.lock
+#   Both modules are pure declaration (a server container + a templated file) — no module runtime image
+#   is built; the bed only stocks the substrate and the ollama server image.
