Nightly builds will move a rolling `nightly` tag across main. A plain
`git describe --tags` returns whichever tag is nearest, so once that tag exists
every build — including a real release build — would report its version as
"nightly" and lose the release lineage entirely.
Restrict discovery to `v*` so the rolling tag is invisible to versioning:
with a nightly tag ahead of v0.3.1
git describe --tags → nightly
git describe --tags --match 'v*' → v0.3.1-1-gf940087
Land this before the nightly workflow exists, so no build is ever stamped from
the rolling tag.

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.
