+### Step 88 - Chats list interaction states (menu/select/search)
+- Added default overflow menu (`⋮`) state in chats header with Telegram-like quick actions UI.
+- Added long-press multi-select mode for chat rows with:
+  - top selection bar (`count`, action icons),
+  - dedicated overflow menu for selected chats.
+- Added dedicated search-mode state in chats screen:
+  - search field + section chips (`Chats/Channels/Apps/Posts`),
+  - horizontal recent avatars strip,
+  - list filtered by active query.
