Hui Xiao 300fb8cace Add claude md file for deprecated option removal (#14360 )

Summary:
**Context/Summary:**

It's very easy to make mistake in removing deprecated option such as deleting the corresponding entry in type info that breaks backward compatibility or missing tests to test backward compatibility. Example: https://github.com/facebook/rocksdb/pull/14350#discussion_r2834554287. Added a claude md file for that.

Pull Request resolved: https://github.com/facebook/rocksdb/pull/14360

Test Plan: In claude code, prompted for deprecated option removal with this claude md file in a repo separated from my previous deprecation efforts as much as possible and received correct change at one try.
