Finishing a Development Branch

Finishing a Development Branch: Guide completion of development work by presenting clear options and handling chosen workflow.

This skill executes various `git` commands to manage development branches, including running project-specific test commands (`npm test`, `cargo test`, `pytest`, `go test`), determining base branches, merging branches locally, pushing branches to a remote `origin`, creating GitHub pull requests using `gh pr create`, and deleting local branches and git worktrees. It contacts the remote git repository and the GitHub API.
