xint-mcp-credential-tier-separation-required

xint MCP registration must separate tools by credential tier: read_only policy for Phase 1 xAI-only tools (analyze, ai-search, report, article, collections), and a distinct engagement tier with OAuth policy for write operations (like, follow, engage). Registering OAuth-gated write tools under read_only policy causes runtime authorization failures.
