Add unit tests for VexLens normalizer, CPE parser, product mapper, and PURL parser

- Implemented comprehensive tests for VexLensNormalizer including format detection and normalization scenarios.
- Added tests for CpeParser covering CPE 2.3 and 2.2 formats, invalid inputs, and canonical key generation.
- Created tests for ProductMapper to validate parsing and matching logic across different strictness levels.
- Developed tests for PurlParser to ensure correct parsing of various PURL formats and validation of identifiers.
- Introduced stubs for Monaco editor and worker to facilitate testing in the web application.
- Updated project file for the test project to include necessary dependencies.
