esk 0.8.0

//! GitLab CI/CD target — deploys project variables via the `glab` CLI.
//!
//! GitLab CI/CD variables are injected into pipeline jobs. They can be scoped
//! to specific environments and optionally masked in job logs or protected
//! (only available on protected branches/tags).
//!
//! CLI: `glab` (GitLab's official CLI).
//! Commands: `glab variable set` / `glab variable delete`.
//!
//! Secrets are sent via **stdin** to avoid process argument exposure. Each
//! variable is scoped to an environment with `--scope <environment>`.
