- Update NostrConnectService to use nos2x (window.nostr) by default - Fallback to NostrConnect bridge only if nos2x is not available - Update NostrRemoteSigner to use window.nostr.signEvent() for signing - Add TypeScript definitions for NIP-07 window.nostr API - Update documentation to reflect nos2x as primary authentication method - Remove default use.nsec.app bridge URL - All TypeScript checks pass
