Joseph Doherty e6ff39148b FOCAS Tier-C PR A — Driver.FOCAS.Shared MessagePack IPC contracts. First PR of the 5-PR #220 split (isolation plan at docs/v2/implementation/focas-isolation-plan.md). Adds a new netstandard2.0 project consumable by both the .NET 10 Proxy and the future .NET 4.8 x86 Host, carrying every wire DTO the Proxy <-> Host pair will exchange: Hello/HelloAck + Heartbeat/HeartbeatAck + ErrorResponse for session negotiation (shared-secret + protocol major/minor mirroring Galaxy.Shared); OpenSessionRequest/Response + CloseSessionRequest carrying the declared FocasCncSeries so the Host picks up the pre-flight matrix; FocasAddressDto + FocasDataTypeCode for wire-compatible serialization of parsed addresses (0=Pmc/1=Param/2=Macro matches FocasAreaKind enum order so both sides cast (int)); ReadRequest/Response + WriteRequest/Response with MessagePack-serialized boxed values tagged by FocasDataTypeCode; PmcBitWriteRequest/Response as a first-class RMW operation so the critical section stays Host-side; Subscribe/Unsubscribe/OnDataChangeNotification for poll-loop-pushes-deltas model (FOCAS has no CNC-initiated callbacks); Probe + RuntimeStatusChange + Recycle surface for Tier-C supervision. Framing is [4-byte BE length][1-byte kind][body] with 16 MiB body cap matching Galaxy; FocasMessageKind byte values align with Galaxy ranges so an operator reading a hex dump doesn't have to context-switch. FrameReader/FrameWriter ported from Galaxy.Shared with thread-safe concurrent-write serialization. 24 new unit tests: 18 per-DTO round-trip tests covering every field + 6 framing tests (single-frame round-trip, clean-EOF returns null, oversized-length rejection, mid-frame EOF throws, 20-way concurrent-write ordering preserved, MessageKind byte values locked as wire-stable). No driver changes; existing 165 FOCAS unit tests still pass unchanged. PR B (Host skeleton) goes next.
