João Pedro Battistella Nadas b092047ca6 feat: y/Y system clipboard, modal vim dropdowns
- y/Y/yy and visual y now route through vim's "+" register, which
  copies to the system clipboard via the synchronous document
  .execCommand("copy") path — no permission prompt.
- p/P also remapped to "+ register for symmetry; replaces my custom
  navigator.clipboard.readText() action. Browser may still show a
  permission chip on first paste; granting once makes it silent.
- Source / target / model dropdowns get modal vim-style nav:
  default is native typeahead, Esc → normal mode (accent border),
  j/k move selectedIndex, i and / return to search, blur resets.
  Disabled on coarse-pointer devices.
