Lift line coverage back over the 95% floor after the Flutter 3.44.1
merge nudged it to 94.99%. Adds tests for the changeWord/no-op-edit/
empty-paste/word-motion-edge branches in vim_edit_ops, the lone-key
flush path in SequenceMatcher, and the keybindings-ui / vim extension
identity + deactivate paths.

T-205, the resolver foundation for Vim motions (dd, gg, dw, ciw) and
repeat counts (5j). KeymapBinding now holds an ordered chord sequence
(length 1 for the common single-chord case); `keys:` parses a space-
separated spec into that sequence (D-82). Keymap.resolve keeps the
single-chord fast path; a new stateless Keymap.match answers
exact/prefix/none for a pending buffer.
SequenceMatcher wraps that query with a pending buffer, a repeat-count
prefix (leading digits, 0 excluded since it's the line-start motion),
the d-vs-dd timeout case (flush fires the buffered exact), and broken-
sequence recovery (discard, restart on the last chord). It is headless —
no keyboard reads, no event swallowing — so the editor (T-206) can drive
it from Focus.onKeyEvent and act on the result.
Also drops a stray unused import in the Vim indicator test.
