Changelog of @hackage/gbnet-hs 0.1.0.0

Changelog

Optics migration — all record updates use optics composable lenses (&, .~, %~, use, .=)
Zero-copy linear types — ZeroCopy module with mutable thaw/freeze for SequenceBuffer
SequenceBuffer rewrite — vector-based ring buffer replacing IntMap, O(1) insert/lookup
Sub-microsecond packet processing — INLINE pragmas, bang patterns, strict fields throughout
Peer module split — GBNet.Peer split into Internal, Protocol, Handshake, Migration sub-modules (public API unchanged)
Benchmark suite: connection, fragment, security, and reliability groups

Storable serialization — replaced BitBuffer/BitSerialize with zero-copy Storable-based serialize/deserialize (14ns, 70M ops/sec)
deriveStorable TH — generates Storable instances for product types with little-endian wire format
23x faster packet header serialization — zero-allocation poke-based writes (380ns → 17ns)
4.6x faster deserialization — direct memory access via unsafeIndex (73ns → 18ns)
Type-safe domain newtypes: ChannelId, SequenceNum, MonoTime, MessageId
GBNet.Types module as shared home for domain newtypes
Modules renamed: GBNet.Serialize.FastTH → GBNet.Serialize.TH, GBNet.Serialize.FastSupport → GBNet.Serialize
Idiomatic cleanup: Either do-notation, function composition, fmap/toList
Extracted focused helpers from monolithic functions (Simulator, Connection)
Comprehensive test coverage: channel modes, fragment edge cases, security, config validation, delta compression, simulator

Initial release.
