This change enhances the 'issue' command functionality by enabling structured JSON
output for single issue views and introducing a method for output redirection.
**Changes Implemented:**
1. Enables the existing `--output json` flag for single issue commands (e.g., 'tea issue 17'). This flag was previously ignored in this context.
2. Introduces the new `--out <filename>` flag, which redirects the marshaled JSON output from stdout to the specified file.
Feeback more then welcome.
