PostHog generator

[mathieusouflis]

Problem statement

PostHog analytics setup requires SDK installation, provider wrapping (frontend), and event capture helpers (backend). Same boilerplate every time.

Proposed solution

Implement PostHogGenerator in generators/common/posthog.go.

• Name(): "common-posthog"
• Language(): "*"
• Modules(): ["posthog"]

Apply() generates:

• Frontend (React/Next/Vue): PostHog provider wrapper in app entry, usePostHog hook
• Backend: server-side event capture helper function
• .env.example patched to add NEXT_PUBLIC_POSTHOG_KEY= (frontend) or POSTHOG_API_KEY= (backend)
