Initial commit: real-time Amtrak train tracker TUI
Terminal-based dashboard that decrypts and displays live Amtrak train
positions on a braille-rendered zoomable map with state boundaries and
route lines. Includes search/filter, jump-to-train, and per-station
delay status.
41 tests covering crypto, model parsing, viewport math, search, and
UI rendering via TestBackend.
