First alpha release of AI Decoupled. Exposes Drupal's AI chat processors (agents, assistants, and a built-in direct provider pass-through) as configurable HTTP endpoints for decoupled front-ends. - Config entity per endpoint: executor, allowed roles, streaming, rate limiting. - Token-based auth only on state-changing routes (no CSRF token required by the client). - Real SSE streaming where the resolved processor supports it, with automatic JSON fallback otherwise. - Three independent access gates: global permission, endpoint role, processor access() check. - Stable JSON error envelope across all failure modes. Alpha: API and config schema may still change before 1.0.0.
