Complete the final task of the unified TUI shell plan, which had been left
undone: the code dropped F1 in favour of Ctrl+H, but README and the guide
still documented F1 as the full-help key in nine places, and the repository
screenshots still showed the pre-shell UI.
- Replace every F1 reference in README.md and docs/guide.md with Ctrl+H,
including the two ASCII help blocks that mirror runtime output.
- Document the BS/DEL terminal constraint: Ctrl+H is BS (0x08) while xterm
sends DEL (0x7F) for Backspace, so help and text editing do not collide.
- Recapture all five screenshots from the current binary in a real xterm at
120x40, 80x24 and 60x16 using an isolated XDG profile.
Runtime verification in xterm confirms Ctrl+H opens full help while seven
Backspace presses correctly trim typed text, and that every captured screen
carries the header, framed content and bottom-anchored footer.
