🧪 Add Tests for `sietch dedup`

[S4tvara]

sietch dedup is used to handle the deduplication process of the vault:

What needs to be done

• Unit tests: Cover all functions related to the deduplication command.

• End-to-end (E2E) tests: Test different scenarios, such as:

  • Listing a large number of files (e.g., 100 files)
  • Handling multiple folders with similar or identical names
  • Any other edge cases to ensure dedup behaves correctly ( the more edge cases the better)

This issue aims to improve the test coverage and reliability of the dedup functionality.
