Add support for brev open code/cursor commands and default editor setting

- Add cursor utilities in pkg/util/util.go with TryRunCursorCommand, InstallCursorExtension, etc.
- Add personal settings management in pkg/files/files.go for storing default editor preference
- Update open command to support 'brev open <workspace> <editor>' syntax
- Add --set-default flag to configure default editor (code or cursor)
- Remove broken --cursor flag in favor of argument-based approach
- Maintain backward compatibility with existing 'brev open <workspace>' usage
- Add proper error handling for invalid editor types and missing executables
