fix(analyzer): detect OpenSSL 3.x in OpenSSLAnalyzer

[shawnjohnjr]

Summary

• OpenSSLAnalyzer cannot detect OpenSSL 3.x sources today: 3.x defines OPENSSL_VERSION_NUMBER as a macro expression (not a literal hex constant), the existing regex never matches, and the dependency is dropped via engine.removeDependency(). As a result a scan over an OpenSSL 3.x source tree produces no CPE and never matches NVD CVEs.
• This adds a second pattern that captures OPENSSL_VERSION_STR "X.Y.Z" (introduced in OpenSSL 3.0) and tries it before falling back to the legacy OPENSSL_VERSION_NUMBER hex pattern, so 1.x detection is preserved.
• Adds a test fixture (core/src/test/resources/openssl-3x/opensslv.h from OpenSSL 3.5.6) and a parallel test case asserting 3.5.6 is extracted.

Reproducer (before this change)

Scan an OpenSSL 3.5.6 source tree:

dependency-check --scan path/to/openssl-3.5.6 --enableExperimental --format JSON ...

The resulting JSON has no dependency for opensslv.h and no cpe:2.3:a:openssl:openssl:3.5.6:* identifier. After this change the same scan produces:

filePath: .../include/openssl/opensslv.h
versionEvidence.Version Constant = 3.5.6   [HIGH]
softwareIdentifiers: [pkg:generic/openssl@3.5.6]
vulnerabilityIds: [cpe:2.3:a:openssl:openssl:3.5.6:*:*:*:*:*:*:*]

Test plan

• mvn -pl core -am test -Dtest=OpenSSLAnalyzerTest -Dsurefire.failIfNoSpecifiedTests=false — 5/5 pass (existing 4 + new testOpenSSL3xVersionHeaderFile)
• End-to-end CLI scan against an OpenSSL 3.5.6 source tree confirms cpe:2.3:a:openssl:openssl:3.5.6 is now attached to the opensslv.h dependency

Pull request overview

This PR updates OpenSSLAnalyzer so it can correctly extract versions from OpenSSL 3.x source headers, where OPENSSL_VERSION_NUMBER is no longer a literal hex constant and therefore doesn’t match the legacy regex. This ensures OpenSSL 3.x scans produce version evidence and identifiers (e.g., CPE/PURL), enabling NVD CVE matching.

Changes:

• Add detection for OpenSSL 3.x by parsing OPENSSL_VERSION_STR "X.Y.Z" before falling back to the legacy OPENSSL_VERSION_NUMBER pattern.
• Add an OpenSSL 3.5.6 opensslv.h test fixture under core test resources.
• Add a new unit test asserting 3.5.6 is extracted from the OpenSSL 3.x header.

This analyzer is super curious to me given how specific it is. I wonder how many people use it - are you a user? 😅
