[Epic] Finalize and Document v0.1.0 Release

**Background**

With the core functionality, infrastructure, and user experience elements for Version 0.1.0 InDev of Tessitura implemented (as tracked in previous Epics), the final crucial steps involve ensuring the quality, reliability, and usability of the release. This requires comprehensive testing to validate the implementation and clear documentation to guide users.

**Description**

This Epic tracks the essential activities of writing thorough unit tests and creating comprehensive user documentation for the features included in the v0.1.0 InDev release. Completing these tasks is vital for delivering a stable, trustworthy, and accessible initial version of the application.

**Constituent Tasks**

- [ ] Write Unit Tests (#12)
- [ ] Update Documentation (#13)

**Technical Notes**

- Ensure unit tests (#12) provide adequate coverage for the features and command-line options described in the documentation (#13).
- The documentation (#13) should accurately reflect the behavior verified by the unit tests (#12).
- Focus testing on core functionality, edge cases, and error handling implemented in earlier stages.
- Documentation should prioritize clarity for new users, covering installation, basic usage, and examples.
- Adhere to standard Rust practices for testing (`cargo test`) and standard Markdown practices for documentation.

**Acceptance Criteria**

- Both constituent tasks (#12, #13) are completed, reviewed, merged, and closed.
- A comprehensive suite of unit tests (#12) exists, passes consistently, and provides reasonable coverage for the v0.1.0 feature set.
- Clear, accurate, and comprehensive user documentation (#13) is available, covering installation, usage, options, and examples for the v0.1.0 features.
- The documentation accurately reflects the tested behavior of the application.
- The v0.1.0 InDev release is considered sufficiently tested and documented for initial user evaluation or internal use.
