Node script execution causes bouncing icons in macOS Dock

[charlesvien]

Context

Reported by Georgiy Tarasov via Slack. When PostHog Code executes node scripts, extra icons appear and bounce in the macOS Dock.

Problem

Running node scripts from PostHog Code spawns processes that register as separate applications in the macOS Dock, causing icons to repeatedly bounce.

Expected behavior

Node scripts executed by PostHog Code should run in the background without spawning visible Dock icons.
