+### Step 101 - Chat title/profile API parity
+- Added Android API integration for:
+  - `PATCH /api/v1/chats/{chat_id}/title`
+  - `PATCH /api/v1/chats/{chat_id}/profile`
+- Extended `ChatRepository`/`NetworkChatRepository` with `updateChatTitle(...)` and `updateChatProfile(...)`.
+- Wired these actions into the existing Chat Management panel:
+  - edit selected chat title,
+  - edit selected chat profile fields (title/description).
