Welcome. You may find https://notmuchmail.org/contributing/ has some
helpful hints, if you didn't already see it.  In particular, your patch
needs an "meaningful commit message". You seem to have mostly managed to
follow the notmuch coding style, so thanks for that.

As a minor point, this should go under "Command Line Interface", since
hooks are strictly a CLI feature.

"hooks exist."

No real objections to the code or the feature, but you'll need to update
the test suite. In particular T030-config and T040-setup are currently
broken by your patch (but easy to fix).  You should also add at least
test to T400-hooks.sh to ensure running hooks from a non-standard
location works. Feel free to ask for help with the test suite, if
copying existing tests isn't enough.
