/**
 * @purpose Parse CLI arguments for the alt-opinion command.
 * *
 * Parses repeated --model, optional --synthModel, --file, --modelPrompt, --synthPrompt, --strict.
 * Validates provider names, mutual exclusion of stdin/--file, :: syntax for per-model prompts,
 * and minimum model count.
 * *
 * @param rawArgs Raw CLI arguments (typically process.argv).
 * @param [opts] Options bag carrying pre-read stdin content for test injection.
 *   When omitted and stdin is not a TTY, the parser reads stdin synchronously.
 * @throws {Error} On validation failures (missing model, unknown provider, mutual exclusion, etc.).
 * @returns Parsed arguments with resolved artifact content.
 * @sideEffect FS: reads stdin when not TTY and opts.stdinContent not provided. Actual data presence is determined by non-empty trimmed content.
