Fix path validation issue causing CI failures

The real issue was not ora/ESM - it was the path validation logic.
- Removed overly strict path sanitization for output directories
- Absolute paths (used in CI tests) now work correctly
- Relative paths are simply resolved without unnecessary validation
- The PathValidator.sanitizePath was rejecting valid paths

This fixes the 'Invalid output directory: Unknown error' that was
occurring in CI when tests used absolute temp directory paths.
