add nostr.repo-relay-only config to limit publishing to repo relays

Adds a git config key nostr.repo-relay-only that, when set to true, causes
nostr events to be sent only to the repository's own relays, skipping the
user's personal write relays and default/blaster relays. Useful for
repositories that should not broadcast to the maintainer's personal relay set.
Set persistently via \`git config nostr.repo-relay-only true\` or in one step
with \`ngit init --repo-relay-only\`.
