A VS Code extension for GitLab: GitLab Workflow

What this post added

This post details the development of the GitLab Workflow VS Code extension. It covers the initial iteration of displaying assigned issues and merge requests, followed by further iterations that added features like pipeline status display in the status bar, advanced pipeline actions (view, create, retry, cancel), issue and MR search, viewing MRs and closing issues from the status bar, opening active files with line highlighting, creating snippets, comparing branches with master, and validating `.gitlab-ci.yml` files.
