Add slices + speech_regions modules
- slices.py: extract overlapping audio chunks for manual review (filename
embeds start/end timestamps for easy reference)
- speech_regions.py: find/extract only the speech regions (silence stripping),
useful as a faster-whisper pre-processing step
- waveform.py: fix silencedetect verbosity (info, not error) + regex parser
to handle '[silencedetect @ 0x...] silence_start: 0' prefix
- cli.py: new 'slices' subcommand
- tests: 12 new tests (slices, speech_regions, regex); 61 total all passing
- README: updated with subcommand table + step-by-step workflow
