The self-hosted iroh-relay at stargaze.whatdoyouliketodo.com was no longer reachable (Caddy up, iroh-relay daemon down), producing 'Failed to connect to relay server' warnings on every startup. Remove RELAY_ZODIA, ALL_RELAYS, and BOOTSTRAP_NODE_ID and let iroh use its public default relays. Delete the zodia-bootstrap binary and service unit — no longer needed.
