## Message

```
edit_prediction: Fix v4 cursor placement (#61901)

# Objective

Prevent accepted v4 edit predictions from moving the cursor past the
model's predicted position.

## Solution

Keep the cursor's base anchor fixed while applying inserted text, then
apply the model-provided offset. Add regression coverage based on the
reported cursor jump.
