Add matcher packages and OpenID4VP config defaults

[Wicpar]

Summary

• Splits matcher packages from the base Expo module while keeping the base package focused on low-level DC API bindings.
• Updates the Aptitude matcher package with the latest rebuilt WASM bundle.
• Adds TypeScript defaults so registerCredentials() and encodeAptitudeConsortiumConfig() work with omitted config.
• Models OpenID4VP feature support as support lists for request protocols, response modes, response types, query methods, and request parameters.
• Adds typed selection helpers exposing per-slot metadata, including associated transaction data and whether it was displayed.
• Documents config, defaults, transaction data validation, payment/SCA display mapping, and selection metadata in a shorter package README.
