V8 CiderG Path Adjustments

Because CiderG nests the V8 repository as a component of a larger Chromium checkout, the build output (out/ directory) is generated at the root of the Chromium checkout rather than the V8 directory.

Path Rules

• When executing from chromium/v8, the build directory is located one level up at ../out/.
• Adjust any relative binary or test runner paths accordingly.
  • Incorrect: out/x64.debug/d8
  • Correct: ../out/x64.debug/d8
