`mdtablefix` unb0rks and reflows Markdown tables so that each column has a uniform width. When the `--wrap` option is used, it also wraps paragraphs and list items to 80 columns.
Scenarios live under `tests/features/`. Step implementations in `tests` share \
a common `World` struct that uses `figment::Jail` for isolation. Each scenario
demonstration example \
executes asynchronously with `tokio`.
