CydandClaude Fable 5 e590b89c47 Keyboard and Xbox-gamepad input drive the panel
New input pipeline: sources feed an InputRouter (VRio.Core.Input) that
calls the same VRioDevice press/release/axis entry points the mouse
canvas uses, so routed input is indistinguishable on the wire.

- Bindings live in %APPDATA%\vRIO\bindings.txt (plain text, commented
  defaults written on first run; Reload/Edit buttons in the new Input
  group). Keys and pad buttons press any RIO address, momentary or
  toggle; axes bind in normalized units of each axis realistic travel
  window with deflect (spring-back), rate (position holds), deadzone,
  and invert options - RioAxisRange supplies the wire signs.
- Router suppresses key auto-repeat, edge-detects pad buttons, and
  hold-counts per address so overlapping sources press once and
  release last; axes only write when the composed value changes, so
  mouse drags keep working while sources idle.
- Xbox pad via a zero-dependency XInput P/Invoke poller (xinput1_4,
  fallback xinput9_1_0), throttled rescan while disconnected.
- MainForm intercepts bound keys in ProcessCmdKey so arrows/space
  reach the panel instead of moving focus; keys release on focus
  loss; center-axes and host ResetRequest reset the rate integrators.
- Canvas highlights router-held addresses like clicks.
- Defaults: arrows=stick, W/S=throttle, Q/E=pedals, numpad=internal
  keypad, IJKL/Space=hat+main; pad left stick/triggers/right stick =
  stick/pedals/throttle-rate, ABXY/dpad/shoulders = named buttons.
