Add an option in Preferences to disable syntax highlighting globally

[lobre]

Problem

Currently, Code always applies syntax highlighting based on the detected or selected language.

The only way to disable it for a given file is to manually change its language mode to “Plain Text”, but it must be done per file, every time.

For users who prefer a minimal, distraction-free interface, this is not ideal.

Personally, I’ve developed the habit of working without syntax highlighting — I find it helps me focus on code structure and readability rather than colors. While I understand this is a subjective preference, a global toggle would make Code more flexible for different workflows.

Proposal

Add a setting in Preferences as as:

[ ] Disable syntax highlighting
