SDK reports where an API key actually came from

The SDK now reports where an API key really came from, like the env var or an apiKeyHelper.

What

The credential-source values in the SDK schema now lead with what current CLIs really emit: ANTHROPIC_API_KEY, apiKeyHelper, /login managed key and none. The previous set (user, project, org, temporary, oauth) remains only as documented legacy so existing types keep compiling.

Evidence

'user' | 'project' | 'org' | 'temporary' | 'oauth' are legacy members that current CLIs never emit

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
