fix(ai): make sure ShowSelection works

[YousefED]

Summary

The showSelection(false) effect cleanup in the Link button was interfering with the AI extension. What happened:

• formatting toolbar opens
• user clicks AI Extension
• AI Extension opens and sets showSelection(true)
• Formatting toolbar closes and link button unmounts, calling showSelection(false)

Rationale

This keys the showSelection by "consumer". @nperez0111 let me know what you think if this, open to other solutions

I think I would prefer a slightly different approach here:

commands:

• showSelection(key: string)
• hideSelection(key: string)

But, honestly it is a minor thing. I would probably revisit the naming of this altogether on second though. Like PreserveSelectionExtension with show & hide methods

But, I'd rather just fix the bug for now and revisit later
