Original task statement excerpt

Stale Anthropic OAuth credential blocks requests after #3952 removal
## Problem

After upgrading through v2.74.0 (#3952, which removed Anthropic OAuth for TOS compliance), users who still have a `type:"oauth"` credential under `anthropic` in `auth.json` hit a hard error on every request to an Anthropic-provider model:

> Your Anthropic credentials were set up via OAuth, which is no longer supported. Please re-authenticate: run '/login', select 'Paste an API key' → Anthropic. Alternatively, switch to the Claude Code CLI provider.

This error was introduced in #4308 (commit `2dab94ad0`) as a clearer replacement for the previous generic cooldown error. However it does not clean up the stale credential, so:

- `hasAuth("anthropic")` keeps reporting true, masking the correct "no key configured" fallback.
- Users with a working local `claude` CLI can't transparently fall back — the stale OAuth entry keeps the request routed through the Anthropic provider path.
- The only remedy today is to hand-edit `auth.json`.

## Expected

When stale Anthropic OAuth is detected:

1. Self-heal: strip only the `type:"oauth"` entry, preserving any `api_key` credentials.
2. If the `claude` binary is in PATH, surface an actionable message directing the user to switch their model's provider to `claude-code`.
3. Otherwise, surface a "no key configured" style message.
