+
+Introduce shared libraries and extension points for future isolation of LLM providers in dedicated backend modules.
+
+This change also updates the public API surface for provider-related base classes/types and shared MCP chat types:
+
+- Move provider base classes and provider-related Node/backend integration types out of `@alithya-oss/backstage-plugin-mcp-chat-backend` into `@alithya-oss/backstage-plugin-mcp-chat-node`.
+- Move shared/common MCP chat types out of `@alithya-oss/backstage-plugin-mcp-chat-backend` into `@alithya-oss/backstage-plugin-mcp-chat-common`.
+- Consumers importing these APIs from `@alithya-oss/backstage-plugin-mcp-chat-backend` should update their import paths to the new packages above.
+
+No functional behavior is changed, but downstream consumers may need to update imports to compile against the new package structure.
