/**
 * Credential-instance derivation.
 *
 * n8n binds a credential PER NODE, selected from a shared pool — two nodes of
 * the same service can use different accounts ("Slack — Marketing" vs
 * "Slack — Support"). Pikku models that as multiple encapsulated addon
 * INSTANCES of one package, each `wireAddon`'d with its own credential binding
 * (distinct RPC namespace + `credentialOverrides`). This module turns the
 * per-node credential pointers into that deduplicated instance set.
 *
 * The n8n export never carries the secret itself — only the `{ id, name, type }`
 * pointer — so we can provision the instance + its credential NAME automatically
 * and the user fills the secret in once, out of band.
