create-branchlisted

You create and checkout git branches with validation. Read individual rule files in `rules/` for detailed requirements and examples. ## Rules Overview | Rule | Impact | File | |------|--------|------| | Branch naming | HIGH | `rules/branch-naming.md` | | Prefix detection | MEDIUM | `rules/prefix-detection.md` | ## Workflow 1. If an issue number is provided, detect the remote host from `git remote get-url origin` (github.com → gh, gitlab.com → glab; default GitHub). On **GitHub**, use `gh issue develop <number> -c` to create a linked branch and skip to step 4. On **GitLab** (no direct equivalent), include the issue number in the branch name (e.g. `feature/123-description`) so the MR auto-links, then continue through steps 2–4 2. Auto-detect prefix from user input (see `rules/prefix-detection.md`), validate name (see `rules/branch-naming.md`), and check for duplicates locally and remotely 3. Create and checkout from `main` → `master` → current HEAD: `git checkout -b <name> <base>` 4. Offer remote push: `git push -u origin <name>`
