The `[llm]` reference now describes `enabled`, `api_key_url`,
`stands_in_for`, `small_default`, `probe`, `family`, and the cutoffs as
lithos fields, the coding harness under `metadata.agent`, and the secret
names lithos derives for operator-defined providers. Secret-bearing
headers go in `default_headers` as `{{ secrets.NAME }}` tokens. The
integration guides enable a provider with `enabled = true` on its table.

lithos-llm now owns which named secrets each provider reads and how they
shape into its auth scheme, including a derived `<PROVIDER>_API_KEY` for
operator-defined providers. Fabro's job shrinks to supplying the store:
`VaultCredentialSource` hands lithos a lookup that reads the process
environment, then the vault, under the same conventional names.
What Fabro still adds on top: the Codex OAuth credential in the vault,
refreshed and persisted when it expires; `{{ secrets.NAME }}` tokens in a
provider's `default_headers`, resolved against the vault and re-sent as
credential headers; and OpenAI organization and project headers from the
environment.
Deleted with the `metadata.fabro.credentials` list: `CredentialRef`,
`CredentialResolver`, `EnvCredentialSource` (now
`VaultCredentialSource::environment_only`), and the `env_var_names` /
`expected_vault_secret_name` helpers, replaced by `secret_names` and
`expected_secret_name` over the lithos table. `openai-codex` joins the
first-party provider id constants.

fabro-model's ids and billing rollup now live in fabro-types, and its
pricing, catalog, provider TOMLs, and legacy index are replaced by the
lithos built-in catalog plus the Fabro policy layer.
Regenerate the configuration reference for the `[llm]` overlay and
`metadata.fabro`, and rewrite the SDK, models, and integration docs for
the lithos provider and model shapes.
