📚 Description

This pull request addresses issue #1127 by moving CrankyTokenFilter from the incorrect namespace:

• Old Namespace: Lucene.Net.TestFramework.Analysis.CrankyTokenFilter
• New Namespace: Lucene.Net.Analysis

✅ Details:

• Updated the CrankyTokenFilter class to reside in the Lucene.Net.Analysis namespace, aligning it with the correct package as in the original Lucene project (org.apache.lucene.analysis).
• Ensured that the class remains in the TestFramework project and was not moved to Lucene.Net.Analysis.Common.
• Adjusted any necessary using statements and references.

---

🧪 Tests

• Unit tests covering CrankyTokenFilter have been run successfully.
• Verified that all tests related to this change pass without regression.

---

📚 Documentation

• Updated inline comments where necessary to reflect the namespace change.
• No public-facing documentation changes required.

---

🎯 Checklist

• I've read the [Contributor Guide](https://github.com/apache/lucenenet/blob/main/CONTRIBUTING.md) and [Code of Conduct](https://www.apache.org/foundation/policies/conduct.html).
• Unit/integration tests were added or updated.
• Verified no breaking changes were introduced.

🔥 Ready to Merge!

This change ensures that the project structure remains consistent with the original Lucene package, maintaining correctness and improving maintainability.

Hi Paul, Thank you for reviewing and merging my PR! I'm excited to continue contributing to Lucene.NET and explore more ways to improve the project. Apologies for the delayed response — I’ve been busy learning more about the GSoC proposal process and exploring Lucene.NET’s source code to better understand the project. I also wanted to mention that the GSoC proposal submission period has now started, and I’m eager to submit a well-structured proposal aligned with Lucene.NET’s goals. I look forward to your guidance and any feedback that can help strengthen my proposal. Best regards, *Nehan Pathan*
