Don't announce any addresses with temporary repo

davidebeatrici · davidebeatrici · commit 85e2c0a65c29 · 2026-01-24T22:10:04.000+01:00
Previously all detected IP addresses were announced!

In addition to being a potentially serious privacy/security issue, that behavior poisons content retrieval because the node is only alive as long as download is in progress.
