/**
 * Builtin {@link ProviderDef} set — the SEED SOURCE for the `providers` table.
 *
 * M3 Provider SSoT (epic T11667 · task T11703). The DECLARATIVE provider definitions
 * are DERIVED from the existing runtime {@link ProviderProfile} builtins (the in-process
 * registry SSoT) rather than re-declared — so the two never drift and there is one
 * place to add a provider (the profile). `toProviderDef` projects a `ProviderProfile`
 * (which bundles non-serializable hook closures) down to the serializable `ProviderDef`
 * shape (DATA only): identity + aliases + auth + endpoint(s) + catalog key + headers +
 * env vars + OAuth placeholder + the declarative request quirks.
 *
 * ## Why this lives under `provider-registry/`
 *
 * The builtin profiles are model-data SSoT (the LLM-chokepoint lint exempts this
 * directory for model-id literals). This module reads their declarative DATA and
 * never constructs a transport/client — it carries no model-id literals of its own.
