Codebase improvements

This ticket serves as the overarching task for a series of sub-issues focused on refactoring and enhancing our codebase.
## The primary objectives of this initiative are to:
- Improve Code Quality: Clean up and standardize code to make it more readable and maintainable.
- Increase Code Efficiency: Optimize existing logic and eliminate redundancy to boost performance.
- Enhance Performance: Identify and address performance bottlenecks for a smoother user experience.
- Reduce Future Roadblocks: Proactively address technical debt to facilitate faster development and easier integration of new features.

## Key Areas of Focus:
- Refactoring: Systematically review and restructure existing modules for better modularity and clarity.
- Optimization: Identify performance-critical areas and apply targeted improvements.
- Best Practices: Implement coding standards and practices that reduce technical debt and improve long-term maintainability.
- Testing & Documentation: Enhance test coverage and update documentation to support the changes.

This parent ticket will house all related sub-issues, each addressing specific parts of the codebase. Together, these efforts aim to build a more robust, efficient, and scalable system, paving the way for smoother development cycles and fewer obstacles down the line.

Let’s use this ticket as a centralized point to track our progress on codebase improvements and ensure that our technical foundation remains solid as we scale.

This is an overarching parent ticket rather than a self-contained change, and it names no files, tests, or entry points. Start by finding the related sub-issues and select a specific, scoped task; done means completing that sub-issue with the requested code, tests, or documentation changes.
