//! GitHub Actions target — deploys repository secrets via the `gh` CLI.
//!
//! GitHub Actions secrets are encrypted environment variables available to
//! workflow runs. They are stored using libsodium sealed-box encryption on
//! GitHub's servers.
//!
//! CLI: `gh` (GitHub's official CLI).
//! Commands: `gh secret set` / `gh secret delete`.
//!
//! Secrets are sent via **stdin** to avoid process argument exposure. Supports
//! an optional `-R <owner/repo>` flag to target a specific repository (defaults
//! to the current repo).
