- Add isAlias() helper to identify 'default' and 'communications' aliases
- Prefer actual device IDs (long strings) over alias IDs
- For alias deviceIds, use {audio: true} to let system choose
- For real deviceIds, try exact first, then ideal as fallback
- Add debug logging for isSecureContext and alias detection
This fixes the "Could not start audio source" error when Electron tries
to open a microphone using exact: 'communications' constraint.
