Adds client-side PostHog tracking to run in parallel with server-side telemetry across studio, docs, and www. This enables session replays and resolves a race condition where page views arrive before group assignments resulting in attribution errors.
Changes:
- Created PostHog client wrapper with consent-aware initialization in common package
- Integrated PostHog client calls into existing telemetry functions to send events to both PostHog (client) and backend (server)
- Updated CSP to allow connections to PostHog endpoints
- Added environment variable support for all apps
- PostHog client accepts consent as a parameter and respects user preferences
- Events can be distinguished in PostHog by $lib property (posthog-js vs posthog-node)
- PostHog URL configured based on environment (staging/local uses ph.supabase.green)
- Maintains full backward compatibility with existing telemetry system
