[Epic] Enhance Terminal User Experience (UX)

**Background**

For Version 0.1.0 InDev of Tessitura, providing a clear and informative user experience within the terminal is crucial for usability. After processing directory data, the application needs to present this information effectively. Furthermore, during potentially long-running scanning operations, users require feedback to understand the application's status and progress. This Epic addresses these critical aspects of the terminal presentation layer.

**Description**

This Epic tracks the development efforts focused on improving how Tessitura interacts with and presents information to the user in the command-line environment. It specifically covers the design and implementation of the visual output format for directory structures and the addition of progress indicators during processing. The goal is to make the tool intuitive, informative, and pleasant to use.

**Constituent Tasks**

- [ ] Design Terminal Output Format (#9)
- [ ] Add Progress Indication (#10)

**Technical Notes**

- Ensure the progress indication system (#10) integrates cleanly with the terminal output (#9), preventing display conflicts or corruption (e.g., progress bar should ideally clear before final output is printed).
- Strive for visual consistency in style and information density between progress feedback and the final output format.
- Prioritize clarity, readability, and performance in both terminal rendering components.
- Keep presentation logic (output formatting, progress bars) decoupled from the core data gathering and structuring modules.

**Acceptance Criteria**

- Both constituent tasks (#9, #10) are completed, reviewed, merged, and closed.
- The application outputs directory structures in a clear, hierarchical, and readable format as defined in #9.
- Appropriate progress indicators (#10) are displayed during potentially long operations, providing meaningful feedback to the user.
- Progress indicators and final output rendering coexist correctly without interfering with each other in the terminal display.
- The overall terminal user experience is demonstrably improved, offering better feedback and clearer results compared to having no specific formatting or progress indication.
