Integrate plebname (.btc) user search: decentralized, uncensorable and unique aliases for npubs on Bitcoin

[ndee]

Plebnames (http://plebnames.org/) provide completely decentralized, uncensorable and unique aliases for npubs. Only normal Bitcoin explorers like mempool.space or blockstream.info need to be accessed.

Basic example

When you search for a plebname in the top right search bar (e.g. "alice.btc") a lookup in the Bitcoin chain is made (via cors request to arbitrary Bitcoin explorers) to check if there is a Plebname with an attached Nostr npub. If there is one it appears in the search results.

Motivation

Other naming schemes are in some degree centralized and could be corrupted or attacked. Plebnames are as uncorruptible and uncensorable as Bitcoin, because they are stored in the Bitcoin chain and read via normal Bitcoin explorers. How it works is also described in the README.md of https://github.com/MichiSpebach/plebnames, it is a really simple protocol.

Test

The integration can be tested by searching for "test.btc" which returns a valid pleb name with attached npub.

Unless the two .vscode files that where added it looks good. It is straight forward and does not add much weight.

We now host a NIP-05 Provider at https://pleb.name/ that does the lookup in the Bitcoin chain. So searching for Plebnames with @pleb.name (like https://njump.me/ndee@pleb.name) works now on all Nostr clients and pleb.name only does a lookup in the Bitcoin chain like described at https://plebnames.org/. Nevertheless https://pleb.name/ is a single point of failure and could be corrupted and in the long run it is important that Nostr clients do the lookup in the Bitcoin chain by themselves like this pull request proposes.
