Prepares RioJoy.Core for the net40 (Windows XP) target, which has no System.Memory, ValueTask, or System.Text.Json: - IRioTransport and the whole protocol/framing layer now use byte[] + Task (RioPacket.Payload, PacketParser/Builder, RioChecksum, replies, AnalogReport, RioHidReport). At 9600 baud Span bought nothing; the SerialPortTransport bridge copies disappear entirely. - ConfigStore/OverlayTemplateStore switch to Newtonsoft 13 with the same conventions (indented, PascalCase, string enums, null-skipping); verified against the real STJ-written config.json and regions.json (load + round-trip). System.Memory and System.Text.Json packages dropped. 275 tests green. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
