optimize CI efficiency

Optimize CI/CD pipelines by minimizing resource usage and avoiding unnecessary operations. Use lightweight package alternatives when possible (e.g., vim-nox instead of vim for text processing), implement conditional execution to run steps only when relevant files change, and leverage automatic dependency resolution instead of manual listings.

For package optimization, prefer minimal variants:

- name: Install Vim
  run: apt-get update; apt-get install -y vim-nox;

For conditional execution, use file change detection:

- name: Verify Changed Files
  uses: tj-actions/verify-changed-files@v16
  with:
    files_ignore: |
      *.md

For dependency management, use automatic resolution:

- name: Get dependencies
  run: go get -t -v ./...

This approach reduces CI execution time, minimizes resource consumption, and prevents unnecessary workflow runs while maintaining functionality. It’s particularly important for repositories with frequent contributions that don’t affect core functionality.
