Small cleanup PR ready for review: https://github.com/OpenHands/agent-canvas/pull/1204 Removes the staging PostHog key as the default for all non-production builds. The bundle now uses the OpenHands PostHog key unconditionally, and

VITE_APP_ENV

is gone. If you need staging PostHog for testing, set

VITE_POSTHOG_API_KEY

at build time — same key, just not the default anymore. Would appreciate a quick review from anyone familiar with the telemetry/build setup 🐾
