[Bug] Voice mode audio capture fails silently on Linux with PipeWire

Bug Description
Voice mode captures audio (colored bar responds to speech) but nothing happens on release — no transcription, no error, no output. Just returns to normal prompt.

• Claude Code v2.1.74
• Linux: Nobara (Fedora 43), kernel 6.19.2
• Audio: Blue Yeti Nano USB mic, PipeWire, set as default source
• Also tried: Focusrite Scarlett Solo XLR — same result
• bubblewrap installed

Environment Info

• Platform: linux
• Terminal: vte-based
• Version: 2.1.74
• Feedback ID: a38325ad-e04b-4005-a1a0-46a0b0370596
