versionType === "semver-2.0.0": collect invalid values from version, lessThan, lessThanOrEqual, and changes[*].at into badSemVer2. Always rewrite versionType → "semver".
For that same case, if lessThan or lessThanOrEqual equals "0.0.0" or "0.0.0-0", change it to "4294967295.0.0" (top-level only).
versionType === "semver": allow exceptions — version === "0", and any lessThan / lessThanOrEqual that ends with *. In changes[*].at, allow "0" or strings ending with *. Otherwise collect invalid values into badSemVer and set that item’s versionType → "custom".
Items without versionType, or with a different versionType, are left unchanged.
