The transitional cache invalidation code used for migrating to the new
cache format is no longer needed. This change simplifies the codebase
and removes unnecessary cache operations.

Hi @obulat,
Now can you please review the changes

[obulat]

Awesome work, @dryruffian, thank you for your contribution ✨

Why did you need to remove documentation/pdm.lock? If there's no important reason, it's better to remove this change from this PR.

On another note, I see you made the PR from the main branch of your fork. In the future, it's best to create a new branch for your PRs.

I didn't mean to push the change for the documentation/pdm.lock file. It was due to local support issues. we can remove that change from this pull request.

Hello @obulat,
I have tried resetting pdm.lock but i don't think that's working, can you help me with this

This appears to have a number of extraneous changes in addition to the one described in #706, and the import for SearchContext appears to have been changed to a module that does not exist. @dryruffian do you mind limiting the scope of changes to the removal of the cache validation code, and restoring the import to its original location?

I removed the unrelated changes, and also rebased this branch onto the main branch here. If the CI passes, I'll merge your PR.
