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.

Pull request overview

Adds NIP-65 (Relay List Metadata) support by recognizing kind 10002 (relay_list) as a first-class event kind, advertising it via the NIP-11 relay info document, and providing utilities + tests for parsing NIP-65 relay tags.

Changes:

• Add EventKinds.RELAY_LIST = 10002 and advertise NIP-65 support in the relay’s supported_nips.
• Introduce src/utils/nip65.ts utilities (isRelayListEvent, parseRelayList) to parse r tags with optional read/write markers.
• Add unit + Cucumber integration coverage validating replaceable semantics and tag parsing/roundtrip behavior.

@cameri
I had to fix getRelayUptimeSeconds because runCommandWithOutput was rejecting the promise when Docker wasn’t installed. In that case, spawn emits an ENOENT error instead of returning a non-zero exit code, which caused info --json to crash with exit code 1 and broke the pre-commit hook.
I can undo the change and make it as a separate PR if needed

@CKodidela I don't have a strong opinion on that. Do you mind creating an issue to discuss potential alternatives for the getRelayUptimeSeconfs function?

[CKodidela]

Sure will do that.
