Use warnings.warn() for errors instead of print(), show detailed
messages only with --verbose, and simplify user prompts. Keep
error handling consistent with the rest of the codebase.
Add support for transcribing all files in a directory recursively.
The implementation lets ffmpeg handle file validation instead of
filtering by extension. Update README with minimal documentation
for directory support.
