Add fuzzer test for capec_map_enricher.py

[abhijit9040]

This PR adds coverage-guided fuzz testing for capec_map_enricher.py to improve robustness when handling malformed or unexpected JSON/YAML input.

Key changes:

• Added tests/scripts/capec_map_enricher_fuzzer.py using Atheris
• Mocked filesystem I/O and CLI arguments to isolate enrichment logic
• Fuzzed edge cases such as empty catalogs, malformed IDs, and varied version/edition inputs

Reference issue-#2165

It seems like this got lost in a merge? Could you just reset your commit and try to only commit the capec_map_enricher_fuzzer.py‎ file?

Hi @sydseter,

I’ve cleaned up the PR as requested:

• Clean history: Performed a git reset --hard and force-push. The PR now only includes tests/scripts/capec_map_enricher_fuzzer.py.
• Fuzzer update: Switched to patch.object to ensure compatibility with ClusterFuzzLite (PyInstaller) .
• ClusterFuzzLite check: The failure is due to a Docker API version issue in the GitHub runner environment, not related to the fuzzer code.
