Java's version scheme (JEP 322) can contain more than the three numeric
fields SemVer allows, e.g. 18.0.1.1 or 11.0.9.1. normalizeVersion()
rejected these inputs. Convert exact multi-field versions to SemVer build
notation (18.0.1.1 -> 18.0.1+1) before validation, reusing the existing
convertVersionToSemver() helper. Ranges, EA tags, and inputs that already
carry build metadata are left untouched.
