<summary>
Writes a .idx NML index file from a <see cref="T:GsaEditor.Core.Models.GsaArchive"/>.
The index file is XML-compatible and lists each entry with its alias, compression method,
sizes, and data offset for fast lookup without a full sequential scan.
The NML format is the engine's own tag syntax (NOT standard XML):
<code>
&lt;Version=1.0&gt;
&lt;Index=
&lt;Entry=
&lt;ID="path/in/archive"&gt;
&lt;CompLen=123&gt;
&lt;Len=456&gt;
&lt;Offset=789&gt;
&lt;Method="Zlib"&gt;
&gt;
&gt;
</code>
Tab indentation, LF line endings, no BOM. Method is "Zlib" or "Raw".
The engine parses this file to locate entries, so the format must match exactly.
