Subject: [PATCH] fix: stabilize Firo node config to prevent RPC deadlocks
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Restrict to IPv4-only to eliminate hanging IPv6 connections,
reduce max peer connections (125→40), increase RPC work queue
(16→32), and lower dbcache (1024→512) for more frequent flushes.
