Fixed: [bug/lsp]panic: vfs: path is not absolute #670

Added a validation step to filter out empty strings when processing file paths. For example, in the getFileNamesFromConfigSpecs function, validated like this:

for _, fileName := range validatedFilesSpec {
    if fileName == "" {
        continue // Skip empty strings
    }
    file := tspath.GetNormalizedAbsolutePath(fileName, basePath)
    literalFileMap.Set(keyMapper(fileName), file)
}
