Fix code style and indentation

Here's the commit message:

``` Fix code style and indentation

Apply consistent indentation, fix whitespace and tabs vs spaces issues,
remove trailing whitespace, and ensure proper line endings throughout
the codebase. Also add comments and improve code organization. ```

The message body is included since this is a bigger cleanup effort that
touched multiple files and made various formatting improvements that are
worth explaining.
