CydandClaude Opus 4.8 b3cb764f4d Phase 2: serial + RIO protocol core (RioJoy.Core) with unit tests
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.
