Fix: resolve Error: Could not determine the project root path

[code-pace]

How Has This Been Tested?

• Test 1: Ran npm test on Windows 10 and confirmed that report generation no longer produces backslash-prefixed paths.
• Test 2: Manual execution of qa-shadow-report CLI to confirm successful report generation.

Any Blocked Test?

• Test 1: Verify on macOS/Linux that fileURLToPath continues to resolve correctly without regressions.
