1. Most existing CiteTests can be unit tests. They run so much faster
this way.
2. I modified some test cases to cover all trim() in the code.
3. The strict type hint in CiteHooks is removed because the parameter
is not used. Having a hard type hint for what is effectively dead code
makes the code more brittle for changes done outside of this codebase.
