* fix: add missing import and update tests for branch template feature
- Add missing `import { $ } from 'bun'` in branch.ts
- Add missing `labels` property to pull-request-target.test.ts fixture
- Update branch-template tests to expect 5-word descriptions
* address review feedback: update comment and add truncation test
