New no longer echoes the supplied base URL in any configuration error, so
a credential in a rejected URL's query or fragment cannot leak.
llm.NewProviderError now takes the single credential sent with the
request ("" when none) and always keeps a body excerpt bounded to
MaxBodyExcerpt bytes, redacting the credential first. Keyless Ollama
errors therefore keep the vendor's explanation, e.g. model not found.

internal/ai/llm/openai implements Provider over plain net/http against
POST {base}/chat/completions and GET {base}/models, with Bearer auth and
optional extra headers. Structured output uses response_format
json_schema (strict), json_object, or prompt-only with first-JSON-object
extraction, per the configured mode. Usage tokens, model and
finish_reason are parsed.
Errors map 401/403 to ErrAuth, 429 to ErrRateLimited with Retry-After
(seconds or HTTP-date), 408 and transport timeouts to ErrTimeout, and
other non-2xx statuses (and OpenRouter error bodies in a 2xx) to
ErrProvider with a key-redacted excerpt.
Contract tests replay OpenAI, OpenRouter and Ollama /v1 payloads from
httptest servers and assert the key and Authorization value never
appear in an error.
