[FEAT] Default sellers and NIP-65 relay discovery for new users

[BenGWeeks]

Problem

Currently, when a new user visits the marketplace for the first time, they may see an empty shop with no products or merchants. This creates a poor first-time user experience.

Proposed Solution

1. Default Sellers

The marketplace should load with a curated list of default sellers so new users immediately see products:

• LNbits official shop (if available)
• And possibly a small selection of verified/trusted merchants

2. NIP-65 Relay Discovery

Allow logged-in users to discover additional merchants from their own relay list:

• Read the user's relay preferences from their NIP-65 Relay List Metadata (kind 10002)
• Query those relays for marketplace events (NIP-15 kinds 30017/30018)
• Present discovered merchants with an option to add them (or just add them if they choose to just see all products from their relays)

3. User Experience Flow

1. New visitor → Shows default merchants immediately
2. User logs in (via NIP-07) → Option to "Discover merchants from your relays"
3. User can manually add/remove merchants as desired

Benefits

• Better first-time experience
• Personalized discovery based on user's Nostr network
• Maintains user control over which merchants they follow

Perhaps the default sellers could be defined in the admin (authenticated) side of diagon alley.
