/**
 * Issues a command to the GitHub Actions runner
 *
 * @param command - The command name to issue
 * @param properties - Additional properties for the command (key-value pairs)
 * @param message - The message to include with the command
 * @remarks
 * This function outputs a specially formatted string to stdout that the Actions
 * runner interprets as a command. These commands can control workflow behavior,
 * set outputs, create annotations, mask values, and more.
 *
 * Command Format:
 *   ::name key=value,key=value::message
 *
 * @example
 * ```typescript
 * // Issue a warning annotation
 * issueCommand('warning', {}, 'This is a warning message');
 * // Output: ::warning::This is a warning message
 *
 * // Set an environment variable
 * issueCommand('set-env', { name: 'MY_VAR' }, 'some value');
 * // Output: ::set-env name=MY_VAR::some value
 *
 * // Add a secret mask
 * issueCommand('add-mask', {}, 'secretValue123');
 * // Output: ::add-mask::secretValue123
 * ```
 *
 * @internal
 * This is an internal utility function that powers the public API functions
 * such as setSecret, warning, error, and exportVariable.
