- Preserve abort errors while parsing search responses: when the caller's AbortSignal fires after headers but during response.json() (both the success and HTTP-error body parses), surface WEB_ABORTED instead of wrapping it as WEB_PROVIDER_ERROR, so agent cancel/dispose is not misreported as a provider failure. Applied to both the Exa and Perplexity providers. - Report a malformed baseURL as misconfigured in status() (URL.canParse), so selection diagnostics and execution agree (configured-unavailable up front rather than a late WEB_PROVIDER_ERROR). WebProviderStatus already had the reason.
