Add `buzz repos delete` command to remove repository announcements

[abduosmanaj]

Summary

There is no way to delete a repository announcement (NIP-34, kind 30617) via the Buzz CLI. The buzz repos subcommands are limited to create, get, list, and protect.

Use Case

A repository (newworld-career-search) was created by an agent on behalf of the owner and is no longer needed. The owner wants to remove it but has no way to do so — neither the CLI nor the Desktop UI offer a delete option for repos.

In Nostr, deletion is handled by publishing a deletion event (NIP-09, kind 5) referencing the target event. The CLI should support this for repo announcements.

Proposed Solution

Add a buzz repos delete command that:

1. Accepts a repo identifier (--id <d-tag>)
2. Publishes a NIP-09 deletion event (kind 5) targeting the repo announcement (kind 30617)
3. The relay removes or hides the deleted repo

Details

• Repo to delete: newworld-career-search

Interim Request

Please delete the above repo announcement from the ajeeb.communities.buzz.xyz relay, as the owner has no self-service path to do so currently.
