/**
 * Canonical "if you have one of THIS credential type, this is the LLM provider
 * + model the builder may select when auto-resolving." Used by the resolve_llm
 * tool when there's exactly one LLM-provider credential available.
 *
 * Provider strings match the provider IDs used by `@n8n/agents`'s
 * `.model(provider, model)` call.
 *
 * Keep this list narrow — when the canonical default is unclear (e.g. Bedrock,
 * Azure variants), omit the entry so the tool falls through to suspending and
 * lets the user pick explicitly.
 *
 * These are hints, not guarantees. For providers supported by
 * `@n8n/ai-utilities/model-discovery`, `resolve_llm` verifies the model it is
 * about to return — the default included — against the credential's live model
 * list, so a default the provider stops serving degrades to a prompt to pick
 * rather than shipping into an agent config.
