Surfaced by a game (Life is Strange: Before the Storm) that ignores
controller input when it lacks true OS focus even though it still polls
XInput. To find the focus-gated detection path, instrument the hook.
Protocol v3 status back-channel now reports:
- per-slot XInputGetState and XInputGetCapabilities counters (replacing the
single aggregate), so the overlay shows exactly which slots the game polls
and how fast;
- focus-API call counts (GetForegroundWindow/GetActiveWindow/GetFocus) to see
whether the game consults the APIs we spoof;
- input-path diagnostics: whether the process registered Raw Input for a
gamepad usage and whether it set RIDEV_INPUTSINK (background delivery), and
whether a DirectInput dll is loaded.
Host overlay gains a per-slot poll table and an "Input path" section. The DLL
refreshes input diagnostics each worker tick via GetRegisteredRawInputDevices.
hook_selftest updated for per-slot counters; passes.
This is diagnostic-only: once a real run shows which path LiS uses, the
targeted focus fix (e.g. forcing RIDEV_INPUTSINK or DI background coop) follows.
