Port the RIO wire protocol from legacy/riovjoy2.cpp into testable C#: - Protocol/: command + length table, 7-bit checksum, packet builder, and a streaming receive-side framing state machine (PacketParser) that mirrors the legacy ReadCommBlock framing/resync (high-bit-mid-packet abort). Typed RIO->PC decodes: AnalogReport (14-bit sign-extend), VersionInfo, CheckStatus; lamp-state composition. - Serial/: RioSerialLink drives an async receive loop with ACK/NAK reply policy (legacy force-accept vs. opt-in VerifyInboundChecksum), the analog poll timer, and the >5s reset-recovery watchdog. IRioTransport abstracts the COM port; the SerialPort-backed transport does 9600 8N1 + DTR reset pulse, and acquire/release is just create/dispose (foundation for native-game serial yield). - tests/RioJoy.Core.Tests: 54 xUnit tests covering checksum, framing/resync, builder round-trips, analog sign-extension + sentinel rejection, lamp combos, and the read loop driven against an in-memory fake transport. Hardware verification (version/check/analog against a cabinet) remains; it can't be done off-device. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
