🔘 PR Type

What kind of change does this PR introduce?

• [x] Bugfix

📜 Background

With the XverseProvider object being types in sats-connect on the window object, the typing was not extendable and it resulted in typescript clashes.

🔄 Changes

The type was extracted into its own extendable interface in sats connect. This PR requires sats-connect tobe bumped and upgraded and the types are subsequently fixed with the interface correctly extended with the stacks provider.

This is a typing change, so there are no functional changes to test.
