Improve Large File Support (100–300MB log files)

Body

It would be extremely valuable if Zed could handle large files (e.g., 100–300MB log files) more efficiently.

Currently, opening large log files in Zed is quite slow—it takes several seconds to load, and scrolling becomes noticeably laggy. This makes it difficult to use Zed for log inspection during development.

If Zed provided better support for large files, developers wouldn’t need to switch to other tools just to read or search logs. This would significantly improve the development workflow and keep everything within a single editor.

Many other editors already handle large files relatively well, so improving this area in Zed could make a big difference in usability and adoption.
