Linear Release Setup

Generates CI/CD configuration for Linear's release tracking system across GitHub Actions, GitLab CI, and CircleCI. The real value is in the interactive setup workflow that walks you through the pipeline vs. stage decision, which the docs call out as the most common mistake people make. It asks the right questions upfront: what do you ship independently, is each pipeline continuous or scheduled, what's your branching model, how do you version things. Then it fetches the latest README for current commands and flags before writing your config. Handles monorepo path filtering and reminds you about the Docker runtime gotchas on Alpine images. Saves you from setting up one giant pipeline when you actually need three smaller ones.
