[Epic] Implement Core File System Handling

**Background**

For Version 0.1.0 InDev of Tessitura, establishing the core functionality to interact with and represent the file system is paramount. This foundational capability involves traversing directory structures, collecting essential file metadata, and creating an internal representation of this information. It underpins subsequent features related to analysis, visualization, and management of directory contents. Successfully completing the tasks within this epic is critical for the initial milestone.

**Description**

This Epic tracks the implementation of the fundamental components required for Tessitura to understand and model directory hierarchies. It encompasses the necessary steps to scan directories, gather metadata about files and folders, and build an accurate in-memory representation of the scanned structure. The specific implementation details are broken down into the constituent tasks listed below.

**Constituent Tasks**

- [ ] Implement Basic Directory Traversal (#1)
- [ ] Add File Metadata Collection (#2)
- [ ] Create Directory Structure Representation (#3)

**Technical Notes**

- Ensure components resulting from the child issues are designed for modularity and testability.
- Consider overall performance implications for large-scale directory scans when integrating these components.
- Maintain consistency in data handling and error management across the related tasks.
- The final representation (#3) should effectively integrate the traversal logic (#1) and metadata collection (#2).

**Acceptance Criteria**

- All constituent tasks (#1, #2, #3) are completed, reviewed, merged, and closed.
- The system can successfully traverse a specified directory path using the implementation from #1.
- Relevant metadata for files and directories within the traversed path is collected according to the requirements in #2.
- An accurate hierarchical representation of the traversed structure, incorporating the collected metadata, is created and managed by the implementation from #3.
- The core components integrate correctly, providing a cohesive and functional foundation for subsequent development in v0.1.0.
