fix: improve voice mode robustness and add integration tests

- Show TTS errors to user instead of silently logging
- Improve markdown stripping: code blocks, URLs, links, horizontal rules
- Fix stripping order: process markdown links before removing URLs
- Add threading.Lock for voice state variables (cross-thread safety)
- Add 14 CLI integration tests (markdown stripping, command parsing, thread safety)
- Total: 47 voice-related tests
