clippy-strict (nursery redundant_pub_crate, -D warnings) rejects pub(crate)
items inside the crate-private device module; plain pub is equivalent there.
Applied across all platform backends since CI only lints the linux cfg.
- Replaced the miniaudio dependency with custom OS audio device abstractions and backends.
- Implemented platform-specific audio playback and capture for macOS (Audio Queue), Windows (WASAPI), and Linux (PulseAudio/ALSA).
- Added a fallback stub backend returning errors for unsupported platforms.
- Updated audio stream handling with reliable fill guard wakeups and streamlined rate validation.
- Extracted audio capture and playback implementations, along with the WebRTC peer engine, from `pi-natives` into a new `pi-voice` library crate.
- Updated `pi-natives` bindings to consume the extracted `pi_voice` audio streams and live peer core.
- Added release validation gate jobs, parallelized Linux binary builds, and introduced a concurrent macOS release build job in the CI workflow.
- Updated Bazel workspace configurations, Cargo manifests, and documentation to include the new `pi-voice` crate and its dependencies.
