fix(runtime): pass model through to the LLM API instead of dropping it

llm_call_system / llm_call accepted a model argument and discarded it:
they called llm_chain_call(system, user) with no model, and the legacy
ANTHROPIC_API_KEY fallback passed NULL to llm_provider_request, so every
non-agentic chat was pinned to LLM_DEFAULT_MODEL (claude-sonnet-4-5)
regardless of the caller's selection.

Thread model_pref through llm_chain_call: provider-chain entries still
honor their own NEURON_LLM_N_MODEL override and fall back to the
requested model otherwise; the legacy Anthropic path now uses the
requested model. NULL/empty preserves prior default behavior.

Effect: the soul's model selection (state soul_model / SOUL_LLM_MODEL,
e.g. claude-opus-4-8) now reaches api.anthropic.com. Previously the
chat response echoed the selected model in its label while the request
billed Sonnet 4.5.

Not built locally (no elc/cc toolchain on this checkout); needs stage CI.
