Interpolates audio playback time between callbacks using CLOCK_MONOTONIC
for smooth 60Hz updates instead of coarse 8-10Hz steps.
Replaces artificial peak decay with true RMS calculation over 50ms
window. Ring buffer computes RMS directly on internal buffer without
copies for efficiency.
All backends updated with get_callback_state() interface for time
interpolation. Tests passing (34/34).

- wav_dump_backend: Fix data_size double-counting channels (line 126)
- test_wav_dump: Assert on data_size validation instead of warning
- main: Add SIGINT/SIGTERM handlers to finalize WAV on Ctrl+C
- Guard signal handler code with DEMO_HEADLESS ifdef

## Critical Fixes
**Peak Measurement Timing:**
- Fixed 400ms audio-visual desync by measuring peak at playback time
- Added get_realtime_peak() to AudioBackend interface
- Implemented real-time measurement in MiniaudioBackend audio callback
- Updated main.cc and test_demo.cc to use audio_get_realtime_peak()
**Peak Decay Rate:**
- Fixed slow decay (0.95 → 0.7 per callback)
- Old: 5.76 seconds to fade to 10% (constant flashing in test_demo)
- New: 1.15 seconds to fade to 10% (proper visual sync)
## New Features
**SilentBackend:**
- Test-only backend for testing audio.cc without hardware
- Controllable peak for testing edge cases
- Tracks frames rendered and voice triggers
- Added 7 comprehensive tests covering:
- Lifecycle (init/start/shutdown)
- Peak control and tracking
- Playback time and buffer management
- Integration with AudioEngine
## Refactoring
**Backend Organization:**
- Created src/audio/backend/ directory
- Moved all backend implementations to subdirectory
- Updated include paths and CMakeLists.txt
- Cleaner codebase structure
**Code Cleanup:**
- Removed unused register_spec_asset() function
- Added deprecation note to synth_get_output_peak()
## Testing
- All 28 tests passing (100%)
- New test: test_silent_backend
- Improved audio.cc test coverage significantly
## Documentation
- Created PEAK_FIX_SUMMARY.md with technical details
- Created TASKS_SUMMARY.md with complete task report
