+- **Multi-Session Tabs with Independent A2A Bindings** (#8445): Enhanced TUI with
+  multi-session tab support, enabling users to create, switch between, and manage
+  multiple independent sessions within a single instance. Each session maintains its
+  own transcript, persona state, session ID, and A2A binding configuration. Keyboard
+  bindings `Ctrl+N` (new session) and `Ctrl+W` (close session) provided. Session
+  renaming and metadata tracking via `name` and `created_at` fields on `SessionView`.
+  All action handlers updated to operate within the active session context, ensuring
+  full state isolation between sessions while preserving backward compatibility with
+  single-session workflows. BDD test suite added: 10 comprehensive scenarios covering
+  lifecycle, switching, closure, renaming, persona isolation, transcript isolation, and
+  timestamp validation.
