Full Release Notes

# 💪 Added
* feature: Event Detection Log Block by @jeku46 in https://github.com/roboflow/inference/pull/1894
We have new analytics block in workflows - `Event Detection Log Block`
This block takes input from the bytetracker (or any other tracker) and stores a log of events. The events store the time an object (unique tracker id) was first seen, last seen, its tracker id, and class, like shown below:

```json
{
  "1": {
    "tracker_id": 1,
    "class_name": "dog",
    "first_seen_frame": 1,
    "last_seen_frame": 107,
    "frame_count": 102,
    "first_seen_relative": 0.0,
    "last_seen_relative": 3.533333333333333,
    "first_seen_timestamp": 1765744769.0,
    "last_seen_timestamp": 1765744772.5333333
  }
}
Pending events (2):
{
  "5": {
    "tracker_id": 5,
    "class_name": "dog",
    "first_seen_frame": 87,
    "last_seen_frame": 87,
    "frame_count": 1,
    "first_seen_relative": 2.8666666666666667,
    "last_seen_relative": 2.8666666666666667,
    "first_seen_timestamp": 1765744771.8666666,
    "last_seen_timestamp": 1765744771.8666666
  },
  "6": {
    "tracker_id": 6,
    "class_name": "dog",
    "first_seen_frame": 93,
    "last_seen_frame": 105,
    "frame_count": 6,
    "first_seen_relative": 3.066666666666667,
    "last_seen_relative": 3.466666666666667,
    "first_seen_timestamp": 1765744772.0666666,
    "last_seen_timestamp": 1765744772.4666667
  }
}
```

With this block our users can now easily track lifecycle of detected and tracked objects!

* feature: Add Text Display Visualization Block by @rafel-roboflow in https://github.com/roboflow/inference/pull/1895
We have new visualization block in workflows - `Text Display Visualization Block`, users can now add parametrized text element on annotated image, showing live results of other blocks and making it much easier to showcase real value brought by workflow!
