- Fix DisplayTime=0.0f causing flicker on all debug HUDs (now 1.0f)
- Add per-component CVars (ps.ai.ConvAgent.Debug.*) for console debug toggle
- Add MicrophoneCapture debug HUD with VU meter (RMS/peak/dB bar)
- InteractionComponent reuses existing MicrophoneCaptureComponent on pawn
instead of always creating a new one
