Implement NTS (RFC 8915) with KERecord zero-copy frame, PerformKE
(TLS 1.3 + ExportKeyingMaterial), DeriveKeys, and Client state
machine implementing lneto.StackNode. Client handles cookie pool
management, auth body codec with nonce/ciphertext, and two-exchange
NTP flow with UniqueID verification and AEAD authentication.
Add NTS Server wrapping ntp.Server with AEAD verification/sealing,
and HandleKE for server-side NTS Key Exchange over TLS 1.3.
Use internal.LogAttrs for non-allocating structured logging
throughout the NTS client, matching existing conventions.

- 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

* remove old fuzz corpus and stick to using PCG for seeding fuzz test
* polish up drain logic and reduce action search space
* improve fuzzing debug prints
* more fuzz fixes also formatter capture printer fixes
* refactor StackSeeded test
* fix challenge ack infinite packet bug
* more expressive challenge satisfy
* remove printing
* begin adding better fuzz test
* finish adding working fuzzer
* implement mutateipv4
* fuzzer finds a panic in ICMP client on receive empty payload
* rename fuzz tests to reflect fuzz methodology
* begin adding icmp client
* rely on anon structs
* add tests
* tests passing
* icmp fleshed out
* rework icmp to include ip addr
* rename StackAsync.Demux/Encapsulate to RecvEthernet and SendEthernet
* remove legacy unreachable TCP tests
* remove uses of deprecated internet.StackNode in preference of lneto.StackNode
* documentation
* rename methods to signal no I/O happening
* fix: StackBerkeley Bind/Listen/Connect and StackGo dial support
- Bind now stores the bound address; Listen and Connect forward it to
the gostack so the local port reaches SocketNetip.
- Fix StackGo.Socket parsing laddr/raddr instead of zero-value locals.
- Fix inverted isvalid() checks in StackBerkeley.Close causing nil deref.
- Auto-assign ephemeral port for outbound dial connections in SocketNetip.
- Configure tcp.Conn with TX/RX buffers before DialTCP; add DialConfig
fields to StackGoConfig.
