fix: warn and prompt on branch existence during create - #21
Merged
Conversation
Previously `repo create` silently created a new branch from origin/HEAD
when the requested branch name didn't exist anywhere. This caused
confusion when a branch existed on the remote with a slightly different
name (e.g. a typo). Now the CLI warns the user, suggests similar branch
names ("Did you mean?"), and asks for confirmation before proceeding.

Previously, `repo create` silently used an existing remote branch without informing the user. Now it shows branch info (last commit, age) and offers options: use existing, enter a different name, or cancel. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
