docs: clarify stable subpackages + deprecate client-level continuation

+// add a synthetic "Continue." user message, and the eyrie conversation
+// engine (eyrie/conversation.Engine) has its own OutputGroupID-based

+// conversation shapes (no synthetic user turns) and are the recommended
+// pattern for new code. This client-level helper remains for
+// backwards-compatibility with the embedded eyrie HTTP server and
+// non-hawk consumers; new code should implement continuation at the
+// engine or call-site level instead.

+//	github.com/GrayCodeAI/eyrie/client           (Provider interface, message/response types)
+//	github.com/GrayCodeAI/eyrie/catalog         (model catalog: pricing, capabilities, registry)
+//	github.com/GrayCodeAI/eyrie/catalog/registry (ProviderSpec catalog: 16 registered providers)
+//	github.com/GrayCodeAI/eyrie/catalog/xiaomi  (Xiaomi-specific catalog helpers)
+//	github.com/GrayCodeAI/eyrie/config          (provider config + env var resolution)
