Subject: [PATCH] feat: Support naddr format for communikey definition events

Adds support for opening communikey chats using naddr encoding of
kind 10222 communikey definition events, not just bare pubkeys.

Changes:
- Extended parseIdentifier() to detect kind 10222 naddr
- Extracts pubkey (author) as the communikey identifier
- Extracts relay hints from naddr for better connectivity
- Normalizes relay URLs to include wss:// prefix

Users can now open communikeys in three ways:
1. chat naddr1... (kind 10222) - With relay hints from naddr
2. chat npub1xxx - Relays discovered from kind 10222 event
3. chat relay'npub1xxx - With explicit relay hint

The naddr format is preferred as it includes relay hints for faster
resolution of the communikey definition event.
