/**
 * Spawns a child process asynchronously and returns a promise that resolves with the process results
 *
 * This function provides a Promise-based wrapper around Node.js's spawn function with additional features:
 * - Automatic encoding of stdout/stderr as UTF-8
 * - Option to merge stderr into stdout
 * - Option to automatically kill the process on parent exit
 * - Option to provide input via stdin
 * - Verbose logging capability
 *
 * @param command - The command to run
 * @param args - List of string arguments
 * @param options - Configuration options for the spawned process
 * @returns Promise that resolves with the process results including pid, stdout, stderr, status, and signal
 * @throws Will reject the promise if the process fails to spawn or encounters an error
 *
 * @example
 * ```typescript
 * const result = await spawnAsync('ls', ['-la'], { verbose: true });
 * console.log(result.stdout);
 * ```
