Subject: [PATCH] Reduce table caps for client device performance
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Lower known_destinations from 512→128, announce_table from 128→32,
path_table from 256→64. Ratdeck is a client, not a transport node —
smaller tables reduce cull overhead and memory pressure on busy hubs.
