fix: add timing tolerance to test_generate_with_jitter

Relax the lower bound from 3.0 to 2.99 seconds to account for
microsecond-level precision variations in timing checks. The test
was failing intermittently on Python 3.12 with delta values like
2.9999... which are technically valid but fell just under the strict
3.0 threshold.
