Add Turkish translations for CLI and GUI tool sections

**Problem:**
In the CLI tools and GUI tools sections, there are no Turkish translations.

**Goal:**
The goal is to provide Turkish translations for the CLI and GUI tool sections so that Turkish-speaking contributors can fully follow the contribution guide without switching languages.

**Possible solutions**
Translate the CLI tools and GUI tools sections into Turkish while keeping technical terms clear and consistent with the rest of the document.

**Steps to solve the problem:**
- Add CLI and GUI `README.tr.md`
- Translate the content into Turkish.
- Submit a pull request addressing this issue.

Start by locating the CLI and GUI tools sections and reading their existing README files. Add CLI and GUI README.tr.md files with Turkish translations that preserve clear, consistent technical terms; the work is done when both sections are fully available in Turkish.
