Port the iRIO decode and Press_V2/Release_V2 routing into testable C#:
- Mapping/: RioMapEntry decodes the 16-bit map word (lamp/mouse/hat/joy/extended/
alt/ctrl/shift flags + value) and resolves the routing Kind by the legacy
precedence (joy+hat+mouse => RIO command; none => keyboard; else joy>hat>mouse).
RioAddress translates button/keypad events to table addresses (+0x50/+0x60
keypad offsets); RioInputMap is the 112-entry per-profile table replacing the
hard-coded iRIO[].
- InputRouter ports Press_V2/Release_V2: modifier press/release ordering,
scancode keys, joystick buttons, POV hat, mouse move/click (deltas corrected
per PROTOCOL.md), RIO-command dispatch, and lamp feedback (bright on press, dim
on release; RIO commands carry none). InitializeLamps() dims all lamp entries.
- Output is split behind sink interfaces (IInputSink/IJoystickSink/ILampSink/
IRioCommandSink) so routing is pure + unit-tested; Output/SendInputSink is the
real SendInput keyboard/mouse adapter (scancode injection).
- tests: 30 new xUnit tests (84 total) for entry decode, address translation,
and router routing/precedence/lamp/modifier ordering via a recording sink.
The joystick sink's real adapter (HID feeder -> RioGamepad via DeviceIoControl)
is blocked on the Phase 1 driver; routing already targets IJoystickSink.
