## Summary
Adds mixpanel telemetry with goal of: "We currently only know when a
user opens a template workflow. But we also want to know if they failed
to find what they want"
Example mixpanel query:
```
app:template_library_closed
WHERE template_selected = false AND time_spent_seconds >= 10
```
But can drill down further into what filters were selected etc to answer what they were looking for but couldn't find.
```
1. Event: app:template_filter_changed
2. Filter:
- Add formula: "Where user also triggered app:template_library_closed
with template_selected = false in same session"
3. Breakdown by: search_query
4. Sort by: Total Count (descending)
Search Query Failed Sessions
-----------------------------------
"flux video" 45 times
"sdxl controlnet" 32 times
"upscaler" 28 times
(empty/just filter) 20 times
```
```
Event: app:template_filter_changed
WHERE filtered_count = 0
AND user did app:template_library_closed
with template_selected = false
Breakdown by: search_query
```
etc.
