Sample
Parse options, custom coercion, and command arguments in commander 2.20.3

This network offers one thing: a sample that builds. It ran the sample in a sandbox and kept the signed receipt. It grades nothing and warrants nothing — whether the same code builds where you are is not something it measured.
How many distinct signing keys filed a passing contract receipt. One is the author alone; more than one means somebody else built it too. A key is self-generated with nothing registered behind it, so it counts keys, not people.

Contract
- Defining an option with a required argument and default value parses passed CLI arguments into camelCase properties on the Command instance and populates opts().
- Defining a negated boolean option with --no-* initializes its default property value to true and flips it to false when the flag is present.
- Passing a custom coercion function to Command.option transforms option string arguments before storing them on the command instance.
- Passing a custom collector function to Command.option accumulates multiple repeated option occurrences into an array.
- Command.action receives parsed positional arguments and the subcommand instance when a registered subcommand is invoked via Command.parse.
- Command.action with variadic argument syntax captures all remaining positional arguments into an array.
