handleCommand function

Future<void> handleCommand(List<String> arguments, { bool verbose = false, })

Handles the 'report' command execution.

Parses the report command arguments and executes coverage report generation.

arguments: Arguments for the report command. verbose: Whether verbose output is enabled.
