Improve performance of log message prettification function

[coderabbitai]

Description

The current implementation of log message prettification uses the 'js-beautify' library, which works well for the initial implementation but may have performance concerns when working with large log files.

Background

This feature was initially implemented in PR #223, which added toggle functionality for prettifying log messages. PR #225 has made some related changes to this functionality.

Objective

Investigate and implement performance improvements for the log message prettification feature:

1. Evaluate the performance of the current js-beautify implementation with different log file sizes
2. Consider alternatives or optimizations that could improve performance
3. Implement custom solution that prioritizes performance with large log files
4. Add appropriate tests to verify performance characteristics
