feat: add NIP-65 (Relay List Metadata) support

[CKodidela]

Description

Added support for NIP-65 (Relay List Metadata). This includes adding event kind 10002 as a ReplaceableEventStrategy, and implementing utility functions isRelayListEvent and parseRelayList to parse r tags correctly with read and write markers.

Related Issue

Closes #577

Motivation and Context

To support the NIP-65 standard which allows users to advertise their preferred read and write relays, improving interoperability across different clients.

How Has This Been Tested?

I added both unit and integration tests to ensure the feature functions correctly:

• Unit Tests: Added tests for the event strategy factory to ensure kind 10002 is properly treated as a replaceable event. Added tests for isRelayListEvent and parseRelayList to verify correct parsing of tags and markers.
• Integration Tests: Added BDD tests via Cucumber (nip65.feature) verifying the creation, sending, subscribing to, and receiving of relay_list events.
