## Summary by CodeRabbit

* **Bug Fixes**
* Improved synchronization between the Logs Explorer editor and the
URL/search state: running a query now updates the shared search state
(and recent snippets) rather than performing a full route push, and the
editor now prioritizes the URL/state value when present to prevent
mismatches during navigation or query execution.
