ruohki	bad8fba5aa	feat(01-03): implement App struct and event loop with exit behavior ... - App struct with is_login_shell, double-press Ctrl+C state machine, show_quit_prompt - run_event_loop() polls SignalFlags first, then draws, then polls key events - handle_key() suppresses 'q' in login shell mode; double Ctrl+C within 2s quits - draw() renders Phase 1 placeholder TUI with title, welcome text, quit prompt - show_goodbye() prints BBS-style goodbye with 500ms delay after terminal restore - DOUBLE_PRESS_WINDOW const = 2 seconds - mod app added to main.rs	2026-02-28 21:17:10 +01:00
ruohki	966b47edbc	feat(01-02): implement signal handling and logging stub ... - SignalFlags struct wraps Arc<AtomicBool> for SIGHUP/SIGTERM - register_signals() registers SIGHUP and SIGTERM only (not SIGINT) - SIGINT deliberately excluded — handled via crossterm key events for double-press Ctrl+C - should_terminate() polls flag with Ordering::Relaxed for event loop use - init_logging() is a Phase 1 no-op stub with LIFE-03 documentation	2026-02-28 21:12:45 +01:00
ruohki	b258b6d262	feat(01-02): implement terminal init/restore and panic hook ... - init_terminal() enables raw mode and clears main screen via Viewport::Fullscreen - No alternate screen buffer used (deliberate BBS immersive approach) - restore_terminal() disables raw mode and shows cursor using let _ for all calls - install_panic_hook() restores terminal, prints BBS-themed message, delegates to original hook - Use ratatui::crossterm re-export (crossterm is transitive dep only) - All panic hook operations use let _ or eprintln! — no unwrap() or ? inside hook	2026-02-28 21:12:04 +01:00
