[Enhancement request] Color "Executing query…" status for better visibility

[gabriel-r]

When a query is running, the status "Executing query…" is not very visible, and it can be missed if:

1. the user runs the extension for the 1st time, and is not looking for it
2. the query runs in the background and takes more than a few seconds

Please make the status stand out with a strong color highlight, like this

…or this, with only the text color changed, less accessible:

I learned that VS Code's API doesn't directly support custom styling of individual status bar items through standard API calls.

Maybe simply add an emoji or a more visible icon?
