Using `StartsWith` for version comparison is unreliable and could lead to false positives. For example, version '1.0' would incorrectly match file version '1.0.1.2' or '1.00.0'. Consider using `System.Version` for proper semantic version comparison or exact string matching.

Using StartsWith for version comparison is unreliable and could lead to false positives. For example, version '1.0' would incorrectly match file version '1.0.1.2' or '1.00.0'. Consider using System.Version for proper semantic version comparison or exact string matching.

            // Compare versions component-wise for leniency, but avoid false positives
            if (Version.TryParse(plugin.Version, out var expectedVersion) && Version.TryParse(fileVersion, out var actualVersion))
            {
                // Compare only as many components as are present in plugin.Version
                bool matches = true;
                if (expectedVersion.Major != actualVersion.Major) matches = false;
                if (expectedVersion.Minor != -1 && expectedVersion.Minor != actualVersion.Minor) matches = false;
                if (expectedVersion.Build != -1 && expectedVersion.Build != actualVersion.Build) matches = false;
                if (expectedVersion.Revision != -1 && expectedVersion.Revision != actualVersion.Revision) matches = false;
                if (matches)
                {
                    return true;
                }
            }
            else
            {
                // Fallback: exact string match
                if (fileVersion == plugin.Version)
                {
                    return true;
                }
            }
