feat(tui): codex-style input, history, bang commands, single-line status bar

- Arrow-key input history (up/down with multiline awareness) - Bang shell commands via ! prefix (requires --yolo) - Codex-style input bar with mode indicator (R/Y/⌘) - Command palette virtual scrolling - Multiline input viewport fix - Merged model pills + footer into single status line - Removed shift+enter (wait for TUI library support) - Removed default footer hints
