[Option B] Update SimulationLoop to IAudioStrategy

[danieljsinclair]

Issue

Update SimulationLoop to use IAudioStrategy instead of IAudioMode.

Background

Current SimulationLoop uses IAudioMode + IAudioRenderer pair. After consolidation to IAudioStrategy, SimulationLoop needs to be updated.

Goal

Update SimulationLoop to use IAudioStrategy interface:

• Replace IAudioMode references with IAudioStrategy
• Update method calls to use IAudioStrategy API
• Maintain all existing functionality
• Keep tests GREEN

Implementation Plan

1. Update SimulationLoop.h to use IAudioStrategy* instead of IAudioMode*
2. Update SimulationLoop.cpp to call IAudioStrategy methods
3. Remove IAudioRenderer references (now part of IAudioStrategy)
4. Update createStrategy() factory calls
5. Ensure all telemetry/diagnostics still work
6. Run all tests and verify GREEN

Acceptance Criteria

1. SimulationLoop uses IAudioStrategy instead of IAudioMode
2. All IAudioMode references removed from SimulationLoop
3. All existing SimulationLoop tests pass
4. All smoke tests pass (--sine, --threaded, --sync-pull)
5. Clean build with no warnings
6. No behavioral changes (audio sounds identical)

Testing

• All existing SimulationLoop unit tests pass
• All smoke tests pass
• Simulator-level audio tests produce identical output
• Integration tests pass
