API client providers (coreApiClientProvider, tatlockApiClientProvider) now use keepAlive: true.

The AuthInterceptor stores a Ref that became invalid when the provider auto-disposed after a one-time read. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
