strop v0.26.0

Fixed

• gb/gB work in Visual mode: occurrence seeding enters Visual, so
  the repeat key must dispatch there — the visual walker now runs
  visual-section Leaf rows (with the path replayed into the grammar on
  fall-through, so gg & friends parse whole), and keymap rows declare
  their modes (sections), letting one binding live in both.

Added

• The symbol picker renders a colored kind chip before each row
  (fn, struct, enum, mod, …) — the icon column without an icon
  font. Rows slim to name · container · line.
