chore: upgrade golangci-lint configuration and optimize codebase (#4236)

This PR includes the following changes:

- **Upgrade `.golangci.yml`**: Updated the configuration file to align
with the latest golangci-lint version, ensuring compatibility and
leveraging new features.
- **Refactor GitHub Action workflow**: Modified `golangci-lint.yml` in
the GitHub Actions workflow to reflect the updated configuration and
improve CI performance.
- **Codebase optimization**: Refactored code to address issues and
warnings raised by the updated golangci-lint rules, including:
  - Improved function length and complexity.
  - Enhanced error handling and variable naming conventions.
- Fixed minor issues such as unused imports and formatting
inconsistencies.

These changes aim to maintain code quality, ensure compatibility with
the latest tools, and improve overall maintainability.
