[Feature request] Integrate Default Syntax Highlighting Configuration Files into the EXE to Improve Startup Speed

Is there an existing issue for this?

• I have searched the existing issues

Description of the Issue

The default syntax highlighting files include three XML files: stylers.model.xml, langs.model.xml, and DarkModeDefault.xml.
• By default, the first two files are loaded.
• When in dark mode, the latter two files are loaded.

By embedding these files into the notepad++.exe, the startup speed can improve by approximately 30ms compared to using external XML files.
• Compression: Use LZ4 compression for embedding the resources. When loading, the resources are decompressed. This reduces the XML loading time from approximately 60ms to 30ms.
• Without Compression: If LZ4 compression is not used, the loading time can be further reduced. However, this would increase the size of the EXE slightly.

If users modify these configurations, the changes will be saved to external XML files. On the next startup, the application will load the configuration from the external XML files instead of the embedded resources.

Describe the solution you'd like.

Anything else?

No response

Trace startup loading of stylers.model.xml, langs.model.xml, and DarkModeDefault.xml in notepad++.exe, including how modified external files are selected. Compare embedded-resource approaches with and without LZ4, then verify that unchanged defaults load from the executable, modified configurations still override them externally, and startup timing improves.
