Co-authored-by: Jakob Nybo Andersen <jnandersen@proton.me>

Code changes after LLM review (#13)

* Add `Base.copy!` method

* Changes after code review

- Add Aqua quality checks to test targets and run Aqua in test suite.
- Tighten docs/test setup: add docs source path override and update tests for
  merge!/copy behavior and typo fixes.
- Fix auxiliary parsing/validation logic (hex digit range, Int64 parsing for SAM
  integers, and start-index bounds checks in SAM/BAM constructors).
- Simplify auxiliary copy implementation to preserve concrete type while
  avoiding unnecessary conversions.
- Clean up API/docs text and repository agent guidance files
  (add AGENTS.md and CLAUDE.md; remove .JuliaFormatter.toml).
