Show recommendation buttons instead of push/PR buttons after setup script execution

- Filter out environment events when determining which suggestions to show
- Environment events (like setup script execution) are infrastructure-related
- Only show action suggestions (Push to Branch, etc.) when there are actual user/agent interactions
- Show chat suggestions (recommendation buttons) when there are only environment events
- Update posthog tracking to use userAgentEvents for consistency
