// Semver creates a new semantic version object from a given version string.
//
// Parameters:
//
//    version string - the version string to parse into a semantic version object.
//
// Returns:
//
//    *semver.Version - the parsed semantic version object.
//    error - an error if the version string is invalid.
//
// Example:
//
//    {{ semver "1.0.0" }} // Output: semver.Version object

// SemverCompare checks if a given version string satisfies a specified semantic version constraint.
//
// Parameters:
//
//    constraint string - the version constraint to check against.
//    version string - the version string to validate against the constraint.
//
// Returns:
//
//    bool - true if the version satisfies the constraint, false otherwise.
//    error - an error if either the constraint or version string is invalid.
//
// Example:
//
//    {{ semverCompare ">=1.0.0" "1.0.0" }} // Output: true
