Audio:
- Add AudioPlayback with channel-based cpal output (avoids Send issue)
- Add AudioCapture stub with input device enumeration
- Audio gated behind 'audio' feature flag (needs ALSA/cmake)
- list_output_devices() / list_input_devices() for device selection
- StreamItem::Audio packets forwarded via mpsc channel to cpal callback
i18n:
- Replace all Chinese error messages with English in tsdb
- Replace all Chinese comments/doc strings with English in tscore
- All user-facing strings now in English
Build:
- Add Containerfile.build for containerized builds with audio deps
- CMAKE_POLICY_VERSION_MINIMUM=3.5 workaround for audiopus_sys
- tsclientlib audio feature enabled in workspace (needs cmake)
- 69 tests passing, clippy clean on both audio and non-audio builds
