This commit removes the granular latency metrics collection and histogram visualization functionality across the codebase. The changes include:
- Removing latency histogram tracking from audio input/output processing
- Removing latency histogram UI components and related types
- Removing granular metrics collector's latency tracking capabilities
- Updating Prometheus metrics to use milliseconds instead of seconds
- Removing related tests and benchmarks
- Add LatencyHistogramData interface and implement histogram collection in granular metrics
- Create LatencyHistogram component for visualizing latency distribution
- Update audio metrics events to include histogram data
- Add comprehensive tests for histogram functionality
- Improve error handling for OPUS encoder parameter updates
- Optimize validation cache initialization
- Add new /system/memory endpoint to expose total system memory
- Implement process metrics collection for audio and microphone processes
- Update UI to display real-time process metrics with charts
- Replace environment variable check with CLI flag for audio input server
- Improve audio metrics broadcasting with 1-second intervals
- Add memory usage capping for CPU percentage metrics
