Motivation

• Keep the repository root tidy by grouping sample test files into a dedicated directory.
• Prepare the project for future documentation or tooling that expects test assets to be colocated.

Description

• Create a tests/ directory and move test1.txt, test2.txt, test3.txt, test5.txt, and test6.txt into it without modifying file contents.
• Update README.md to add a "Test data layout" section documenting that sample test files live under tests/.
• No changes were made to the test file contents; the change is purely a layout and documentation update.

Testing

• No automated tests were executed as part of this change.
