Add authenticationMethod to state

[ohjonah]

This PR exposes the authenticationMethod field from the AuthKit JS SDK, allowing consumers to know how a user authenticated.

Changes

• Added authenticationMethod to the State interface and initialState
• Updated handleRefresh in the provider to extract and store authenticationMethod from the refresh response
• Added authenticationMethod to the session equality check to prevent unnecessary re-renders
• Re-exported AuthenticationMethod type for consumer use (authkit-js)

Greptile Summary

This PR exposes the authenticationMethod field from the AuthKit JS SDK through the React wrapper, enabling consumers to determine how a user authenticated.

• Added authenticationMethod to the State interface and initialState in src/state.ts:17,29
• Updated handleRefresh in src/provider.tsx:43,61 to extract and store authenticationMethod from the refresh response
• Added authenticationMethod to the session equality check in src/provider.tsx:133 to prevent unnecessary re-renders when the authentication method changes
• Re-exported AuthenticationMethod type in src/index.ts:10 for consumer use

The implementation is clean, consistent, and follows the existing patterns for other session fields like impersonator. All changes are properly threaded through the state management system.

Confidence Score: 5/5

• This PR is safe to merge with no identified risks
• The changes are straightforward and follow existing patterns consistently. The new field is properly threaded through all necessary components: type definitions, state initialization, refresh handler, and equality checks. No security concerns identified - the field is simply passed through from the underlying SDK without transformation.
• No files require special attention

@ohjonah I just released authkit-js v0.17.0, which included your change to introduce AuthenticationMethod. We'll need to upgrade authkit-js in authkit-react in this PR to get it working.
