flashkraft-tui 0.5.4

//! FlashKraft TUI — binary entry point
//!
//! This file is intentionally thin.  All application logic lives in
//! `lib.rs` and the `tui/` submodules so that examples and integration
//! tests can import from `flashkraft_tui::` without also pulling in the
//! `main` function.
//!
//! ## Dual-mode binary
//!
//! | Invocation                                         | Role                      |
//! |----------------------------------------------------|---------------------------|
//! | `flashkraft-tui`                                   | Normal TUI startup        |
//! | `pkexec flashkraft-tui --flash-helper <img> <dev>` | Privileged flash helper   |
//!
//! The `--flash-helper` branch is entered automatically by
//! [`flashkraft_tui::tui::flash_runner`] via `pkexec`; it writes structured
//! progress lines to stdout and exits without touching any TUI code.
