refactor: migrate SubtitleWriter to infrastructure/subtitle_writer.py
- Extract SubtitleWriter classes (SrtWriter, AssWriter, VttWriter) to infrastructure/subtitle_writer.py - Add create_subtitle_writer() factory function - Remove old SubtitleWriter class and _format_timestamp from conversion_runner.py - Use create_subtitle_writer() factory from infrastructure layer - Add tests/test_subtitle_writer.py with 28 tests covering SrtWriter, AssWriter, VttWriter - All tests match old _format_timestamp behavior
