fix: mark bootstrap relay with is_bootstrap flag to prevent disconnection

The bootstrap relay was being registered with is_bootstrap=false, causing
it to be disconnected when empty. This change adds an is_bootstrap parameter
to register_relay() and passes true when registering the bootstrap relay.

The existing check_disconnects() logic already skips bootstrap relays,
but the flag was never being set correctly.
