Original Pull Request: https://github.com/git-ai-project/git-ai/pull/217

State: closed
Merged: Yes

Realized that all our Git Rewrite ops can ignore blame history before Git AI was installed. In very large and very old repos this can be 100x faster.

v1 of this patch used the timestamp of your first authorship note, but that's a little slow to lookup / flaky. Same benefit and much simpler to just setting the date of Git AI's first release for now. We'll come back to this in 6 months with a faster lookup op (right now looking overrides the gain of a few extra months of history)
