Voice capture is not available in this build. Recompile…

Error message

Voice capture is not available in this build. Recompile with --features voice to enable microphone access.

What it means

Compile-time feature guard: start_recording was called in a build without the `voice` feature, so the cpal microphone code is not compiled in and the request is unconditionally rejected. Not a runtime failure — the binary lacks the capability by build configuration.

Solutions

1. Rebuild with --features voice to enable microphone capture
2. Use a build of the TUI that ships the voice feature
