Hook registry: list installed hooks + call counts in Injection panel

Browse Source 
Add a process-wide hook registry (hook/src/hook_registry) that every hook
module registers its hooks with and bumps a counter from each detour. The
XInput, focus-spoof, and audio render-hooks now register their individual
hooks (XInputGetState/Ex/Caps/SetState; GetForegroundWindow/GetActiveWindow/
GetFocus/WndProc guard; IMMDevice::Activate, IAudioClient::Initialize/
GetService, IAudioRenderClient::GetBuffer/ReleaseBuffer) and count calls.

The worker publishes the table to the host each tick over a new HookStatus
field (protocol v4 -> v5: HookEntry[] + count). The Injection panel shows it
as a collapsible table grouped by subsystem with an installed flag and call
count per hook; coop_audio_probe prints the same table headless.

Verified against Phantom Brave: 13 hooks listed with live counts (focus APIs
polled heavily, GetBuffer/ReleaseBuffer ticking with the audio render loop).
All four tests pass.
