* once focus returns.
*
* The PTY is only ever resized by an explicit client claim (`terminal_input` resize). A freshly
* mounted terminal produces exactly one claim, from terminal-pane's pane-focus reflow effect. If
* that claim is emitted while the app is not actively visible (window blurred / document hidden),
* `handleTerminalResize` drops it — and nothing used to re-send it, leaving the PTY at 80x24
* while xterm renders the real pane size: vim/top squeezed into a corner until the user resizes
* the window.
* mounted terminal starts its claim from terminal-pane's pane-focus reflow effect. Previously, if
* that claim was emitted while the app was not actively visible, `handleTerminalResize` dropped
* it without a retry, leaving the PTY at 80x24 while xterm rendered the real pane size.
*
* The repro is the mundane user flow: with a workspace already showing a terminal, open another
* one and switch to a different app while it spawns. We stage the blur deterministically by
* stubbing `document.hasFocus()` (which `useAppVisible` consults on window focus/blur events)
* instead of racing real OS focus. The first terminal matters: `useAppVisible` only observes
* focus events while a consumer is mounted, so it is what makes the blur visible to the app —
* exactly as in the real flow.
* instead of racing real OS focus.
*
* The assertion reads the PTY's own opinion of its size (`stty size`) with input written
* daemon-side — clicking or typing in the pane would fire the focus-claim path and mask the bug.
