- http/httpraw: cap header slice growth to pre-allocated capacity, fix
benchmark to reuse Header across iterations (0 allocs/op)
- internal/ring: replace TODO panic comments with invariant explanations
- tcp/conn: document truncated-frame offset check
- tcp/handler: replace TODO with net.ErrClosed on RST-closed connection
- internet/stack-udpport: filter incoming packets by remote IP address
when configured via SetStackNode; skip filter for IPv4 multicast
destinations (class D) so mDNS and similar protocols work correctly
