library: expand HashSet::extract_if coverage

adds separate `HashSet::extract_if` tests for empty input, consuming no elements & consuming all elements.

the existing test covered one element `true`/`false` predicates but did not check the empty case or the yielded elements when everything is extracted so this keeps the coverage focused on normal public behavior & avoids testing post panic iterator behavior.

Tested:
- `python x.py fmt --check`
- `git diff --check`
