Improve cmd/bd test coverage from 20.2% to 23.3%

- Fixed TestCLI_Create to handle warning messages before JSON output
- Added tests for formatDependencyType (show.go)
- Added tests for truncateForBox and gitRevParse (worktree.go)
- Added comprehensive CLI tests for labels, priority formats, and reopen
- All tests passing in short mode
