Three independent root causes all produce unhandled Promise rejections
that accumulate in the renderer heap and eventually exhaust it:
1. node-pty Windows backend: WindowsTerminal.kill(signal) throws
"Signals not supported on windows." for any signal argument.
Add killPtyProcess() helper in pty-handler.ts that catches the
Windows signal error and falls back to kill() with no argument.
Update isPtyAlreadyGoneError() in main/ipc/pty.ts to classify
the Windows signal error as an already-gone PTY so it does not
re-throw and propagate to the renderer as an unhandled rejection.
2. Uncaught pty.kill() calls in renderer: three call sites in repos.ts,
pty-transport.ts fire-and-forget window.api.pty.kill() without
.catch(). On SSH disconnect or Windows PTY teardown these produce
unhandled rejections that the crash-diagnostics breadcrumb system
retains in memory without releasing. Add .catch(() => {}) to each.
3. ResizeObserver loop: TerminalPane.scheduleSync ran syncPaneTitleOverlayRects
inside a single requestAnimationFrame, which fires while the browser
is still dispatching ResizeObserver notifications. The resulting React
state update re-triggers the observer, producing a "ResizeObserver loop
completed" error on every resize and potentially freezing the renderer
thread. Switch to a double-rAF so the work defers to the next paint
frame after the observation cycle completes. Also suppress the
ResizeObserver loop ErrorEvent in crash-diagnostics.ts so that
any that slip through do not accumulate in the breadcrumb buffer.
Add .catch(() => callback(undefined)) to the Promise.all in
terminal-link-handlers.ts so SSH-disconnect errors don't flood
the unhandled-rejection count.
