fix(parser): allow missing ignore paths in project YAML configuration

- Modified parseProjectYaml to skip non-existent ignore paths instead of throwing errors
- Added test case verifying optional ignore paths are silently ignored when missing
- Maintained existing behavior for missing source files which still throw exceptions
- Updated version number from 1096 to 1097
