fabro-auth defined its own `CredentialSource` trait beside the lithos
`CredentialProvider`, with a parallel `ResolveError` and an adapter between
them, because lithos had no way to ask which providers a store can serve
right now. It does now: `credentials::readiness`, `ClientBuilder::build_ready`,
and `CredentialError::Unusable`.
- The vault, SQL vault, API-key, and extra-headers stores implement
`CredentialProvider` directly. Material that is present but unusable (an
expired token with no refresh, a wrong-typed vault entry, a header secret
that did not resolve, a store read failure) is `CredentialError::Unusable`
with the operator-facing reason; its `Display` replaces
`auth_issue_message`. `is_configured` is the cheap presence check.
- `fabro_llm::build_client` calls `build_ready`; `FabroClient::auth_issues`
carries `CredentialError`. `fabro_llm::configured_providers` replaces the
per-store `configured_providers` method.
- `CredentialSource`, `ResolvedCredentials`, `lithos_credentials`,
`ResolveError`, and `auth_issue_message` are deleted. Twenty files that
held `Arc<dyn CredentialSource>` hold `Arc<dyn CredentialProvider>`.

The OpenAPI spec adopts the lithos request, response, content part,
tool, usage, and cost schemas. The completions endpoint returns the
lithos `Response` JSON verbatim and SSE carries lithos `StreamEvent`s
verbatim. The models and providers endpoints serve the fabro-types
catalog views, and the install and model-test flows probe providers
through fabro-llm.
The CLI builds its catalog from the operator overlay, drives `fabro exec`
through the server gateway adapter, and parses reasoning effort with the
shared controls. The web app reads content parts as lithos-tagged
objects. The TypeScript client is regenerated.

Quality pass over the intent-producer changes, no behavior changes
intended:
- Move the TOML->JSON scalar conversion into fabro-types as
toml_scalar_to_json_value, next to its inverse, with typed errors and
round-trip tests; the CLI now calls the shared helper.
- Reuse goal_layer_from_args for --goal/--goal-file resolution instead
of a second copy of the exclusivity check and cwd anchoring.
- Delete the dead run_manifest_args helper and the test that kept it
compiling; preflight_manifest_args is the remaining real builder.
- Make run_target_for_environment a pure (provider, cwd) -> target
mapping using is_clone_based(), warning at the call site, and default
the environment id from DEFAULT_ENVIRONMENT_ID instead of a literal.
- Resolve the parent run and retrieve the environment concurrently.
- Drop the ResolvedCommandSettings pass-through struct and the
duplicated parse-error mapping in the project settings presence read.
- Share the environment/workflow-version/git test mocks from the cmd
test support module instead of three per-file copies.
