Subject: [PATCH] fix(desktop): handle async EPIPE on process.stderr

process.stderr can emit async 'error' events with EPIPE that bypass
the existing synchronous try-catch in initConsoleTransport(). This
causes uncaught exception crashes when the parent terminal is closed
while the desktop app is still running.

Add a listener on process.stderr that catches EPIPE errors and disables
the console transport, matching the existing synchronous EPIPE guard
pattern. The listener self-removes after the first EPIPE to avoid stale
references.

Closes #37749
