Create Branch

Handles the full git branch creation workflow with validation, prefix detection, and GitHub issue linking built in. When you reference an issue number, it uses gh CLI to create the branch and link it automatically. Otherwise it analyzes your input for keywords like "fix" or "add" to apply the right prefix, converts everything to kebab-case, checks for duplicates locally and remotely, then creates and optionally pushes the branch. The validation is thorough enough that you can throw messy input at it. Saves the mental overhead of remembering branch naming conventions and the gh issue develop command syntax when you're context switching between tasks.
