feat: improved sbom filename extension handling

[22f1001635]

Summary

This PR fixes SBOM parsing test failures caused by invalid CycloneDX file extensions. It enforces strict extension validation for CycloneDX files and improves error handling while ensuring backward compatibility.

---

Changes Introduced

• Extension Validation:
  • CycloneDX SBOMs now require .json or .xml extensions. Invalid extensions trigger explicit error logging.
• Test Fixes:
  • Updated test cases to use valid SBOM files from the test/sbom directory.
  • Added checks for error logging and empty results when invalid extensions are detected.
• Code Refactoring:
  • Simplified extension validation logic in parse.py.

---

Checklist

• ✅ Code adheres to project standards.
• ✅ Tests pass (including updated SBOM test cases).

---

Steps to Test

pytest test/test_sbom.py -v

Verified

• Tests for invalid CycloneDX extensions log errors and return empty results.
• Valid CycloneDX files (JSON/XML) parse successfully.
