📝 Walkthrough

Walkthrough

This pull request enhances passkey-related error handling by adding documentation URL references to the ClerkWebAuthnError class. The ClerkWebAuthnError constructor is refactored to accept a flexible options object that supports additional fields beyond just the error code. This enables error instances for passkey_invalid_rpID_or_domain to include a docsUrl pointing to Clerk's subdomain authentication documentation. Changes are applied across the expo-passkeys and shared packages, with a corresponding changeset entry documenting patch-level version updates.
