Log Message:
SyncTERM: pure-Wren UI library (Surface compositing, ListView, Pane, App)

Full set of new scripts/ui_*.wren modules plus the C-side Surface
foreign that backs them.  Cells collapses into Surface  a single
wh cell-buffer that's both a linear Sequence (count/[i]/iter) and
a 2D grid (cellAt/putRect/fill).  Per-widget Surfaces composite
into the App's screen-sized backbuffer for a single putRect blit
per frame, eliminating the flicker the direct-screen-write path
showed.

App owns mouse/cursor lifecycle: saves and restores the terminal's
mouse-event mask + CustomCursor on entry/exit, replaces the mask
with exactly the events the UI wants (button-1 click+drag, wheel
up/down), parks the hardware cursor on the focused leaf's
cursorPos, applies CustomCursor.none unless cursorVisible is set
(text inputs to come).

ListView: Surface-backed rendering, scrollbar with proper thumb-
position math, mouse drag follows endY, scroll wheel by 3 rows,
hover ignored.  Cursor pos tracks the selected row.

Ctrl+S menu gets a "Wren Console" entry that synthesizes the
Ctrl+\` keypress through wren_host_dispatch_key  works on
ANSI/curses backends that can't capture the binding directly.

Build: filter *_test.wren, *_demo.wren, and wrentest.wren out of
the embedded scripts so user builds don't carry developer tooling.
