Create Production Pull Request

Goal

Open a safe production promotion PR that:

• targets production
• uses main or master as the head branch
• follows the repository PR template when one exists
• lists the PRs included in the promotion as - #123
• closes only the issues that the included PRs completed (linked with a closing magic word), so the promotion moves them from "In Staging" to "Done"
• uses the title Paso a produccion DD/MM/YY with v2, v3, and so on only when needed

Inputs

• repo (optional: use the repo declared for this skill; otherwise use the current repo)
• head_branch (optional: prefer explicit input; otherwise use main, then master)
• base_branch (optional, default: production)
