fix(server): a logged-out Claude CLI no longer reports as authenticated

[yordis]

• The Claude capability probe resolves even when the CLI has no credentials at all, so treating a completed probe as proof of sign-in let provider cards show a healthy authenticated account for an instance that could not run a single turn.
• A logged-out instance now surfaces the same way as every other provider, so the failure is visible where it is configured instead of only when a turn dies.
• Only the CLI reporting no token source at all counts against authentication, because installs that authenticate through an API key, an enterprise profile, or a third-party backend legitimately report an empty account payload and must not be marked logged out.
• The API key source the SDK already reports was being discarded, and reading it is what keeps ANTHROPIC_API_KEY installs from being caught by the new check.

PR Summary

Medium Risk
Changes shared Claude provider auth classification used in Settings and chat; misclassification could wrongly block or allow instances, though behavior is covered by new unit tests.

Overview
Claude provider status no longer treats a successful capability probe as proof of sign-in. claudeAuthStatus interprets the SDK init account payload so Settings and the chat banner can show unauthenticated when the CLI reports tokenSource: "none" with no other credential signals.

The probe now keeps apiKeySource from the SDK (it was dropped before). That field is what keeps ANTHROPIC_API_KEY installs authenticated when they legitimately have no token source. Non–first-party backends (e.g. Bedrock) still count as authenticated even with an empty account shape.

When auth is judged unauthenticated, checkClaudeProviderStatus returns probe status: "error" and auth.status: "unauthenticated" instead of ready/authenticated. Tests cover logged-out first-party, API-key, and third-party backends; fork doc 0015 records the product change.

Walkthrough

Claude capability probing now captures apiKeySource. Authentication status classification covers API keys, tokens, third-party backends, and logged-out sessions. Provider status preserves discovered capabilities while reporting authentication errors.

Tests cover logged-out, API-key, and third-party backend sessions.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to cc5f7

A logged-out Claude CLI can still appear authenticated even when it has no usable credentials, causing users to see a healthy provider and discover the failure only when starting a turn. Merge should wait for the credential check and focused regression test to be completed.

Poem

A rabbit checks the key-source trail,
Finds tokens, backends, without fail.
Logged-out clouds turn status red,
While models hop along ahead.
“Auth is clear!” the rabbit said.
