Three xterm.js features, implemented together because they share the
XtermPane mount + the single attachCustomKeyEventHandler:
- Unicode 11: load @xterm/addon-unicode11, set activeVersion='11' after
the canvas renderer so emoji/CJK/box-drawing widths stop drifting.
- Find in scrollback: @xterm/addon-search + a new per-pane SearchBar
overlay (Ctrl+Shift+F to open, Enter/Shift+Enter next/prev, regex +
case toggles, Esc to close & refocus). Overlay is an absolutely-
positioned sibling in a position:relative wrapper so fit() is unaffected.
- Pane navigation: Ctrl+Alt+Arrow / Ctrl+Alt+HJKL (spatial neighbour via
findNeighborInDirection) and Alt+1..9 (Nth leaf in walkLeaves order).
XtermPane emits a NavigateIntent; App resolves the target leaf and sets
it active, reusing the existing isActive->focusTrigger refocus chain.
All chords live in one attachCustomKeyEventHandler (xterm replaces the
handler on each call). Shortcuts added to shortcuts.ts (SoT for README +
Help), including the Alt+digit shell-conflict caveat. tsc clean apart
from the three not-yet-installed addon modules.
Needs pnpm install on the Windows host + runtime verification.
