fix(terminal): clip xterm canvas overflow during panel resize

abose · abose · commit 4064d399ed38 · 2026-03-02T15:10:22.000+05:30
The xterm canvas has fixed pixel dimensions set by fitAddon.fit().
During drag-resize the terminal content area shrinks but the canvas
retains its old size, visually overflowing into the live preview.
Add overflow: hidden to .terminal-content-area so the canvas is
clipped instantly while the debounced fit adjusts it after the drag.
