 * Regression tests for #3727 — /gsd-code-review N --fix silently no-ops.

 * Root cause: code-review.md `initialize` step parses only --depth and
 * --files flags. --fix, --all, and --auto are never parsed, so no dispatch
 * to code-review-fix.md ever occurs.
 *
 * Fix: add parseCodeReviewFlags() to code-review-flags.cjs (typed IR), wire
 * it into the workflow initialize step, and add a dispatch_fix step that
 * delegates to code-review-fix.md when flags.fix is true.
