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.

Port the analog calibration math and the plasma/VFD command set:
- Calibration/: AxisCalibrator ports UpdateThrottle/UpdatePadal/UpdateJoystick
(riovjoy2.cpp#L1504+) — throttle deadzone + ratchet field, pedal deadzones,
joystick X/Y auto-ranging from observed min/max, rudder mixing (enableZR), and
the per-axis invert flags. Stateful (start positions, last outputs, observed
extremes) like the legacy globals, with the RIOcmd axis resets. Final outputs
clamp to the documented 0..32766 range (also guards a legacy compounding quirk).
AxisOutputs carries the six values; IJoystickSink gains SetAxis(JoyAxis,value)
so calibrated axes reach the HID feeder.
- Plasma/: PlasmaCommands builds the CPlasma ESC sequences (clear/cursor/font/
attr/box draw+fill/text) + GetFontSize + the PlasmaPosText auto-fit/centering;
PlasmaDisplay writes them over the secondary COM transport.
- tests: 21 new xUnit tests (105 total) for throttle proportional/saturation/
invert, pedal ZR mix vs. direct, joystick centering/direction/invert/reset, the
output clamp, and plasma byte sequences/font sizes/auto-fit positioning.
Hardware verification of axis feel + plasma output remains; the game-specific
PlasmaScoreDraw layout is deferred to profile content (Phase 5/7).
