improvise-fo0w. Three black-hole keys closed over vocabulary that
already exists, each mirroring its Cmd line for line with a lockstep case:
- enter-advance (Normal Enter) resolves as cursor arithmetic over
GridExtent; the host's bottom-right AbortChain is Ignored here, which
loses nothing because Enter is never bound inside a Sequence.
- hide-selected-row-item (H) resolves to ModelCommand::HideItem over the
outer row category and the selected tuple's first label, and refuses
on a fold with the host's own FOLD_REFUSAL, now in improvise-protocol.
- search (/) and search-navigate (n) decline out loud as a pair: n needs
the whole model, and / alone would open a box that finds nothing.
NEEDS_THE_HOST drops to exit-search-mode, force-quit and
toggle-group-under-cursor. Tests that used Enter or "Start search" as
their upstream example move to Ctrl-Q and "Exit search mode", including
shell.spec.js's not-sent case.
Also improvise-0629: the help render test now asserts every ex row is
drawn dim, not just that its description is marked.
