 - Add `MultiChoice` to `click_extra.types`: a Click `ParamType` for comma-separated multi-pick from a fixed set of values, the pick-many counterpart to `click.Choice`.
 - Extend the `--show-params` table with seven new columns (`Is flag`, `Flag value`, `Is bool flag`, `Multiple`, `Nargs`, `Prompt`, `Confirmation prompt`).
 - Add the `--columns` option (`ColumnsOption`, `@columns_option`) for SQL `SELECT`-style column selection on both `--show-params` and the standalone `click-extra show-params` subcommand.
