agentty 0.7.2

//! Session lifecycle and prompt E2E tests.
//!
//! Tests cover session creation via `a` key, opening sessions with `Enter`,
//! list navigation with `j`/`k`, deletion with confirmation, prompt input
//! basics (typing, multiline via Alt+Enter, cancel via Esc), and returning
//! to the session list from session view.
