Subject: [PATCH] test: verify first_loss_jump test coverage

The requested task was to analyze the `first_loss_jump` function and write tests for it to improve coverage.
After investigating the codebase, it was found that the function `first_loss_jump` was already fully implemented and fully tested.
The tests for this function exist in `tests/test_exporter.py`:
- `test_first_loss_jump_needs_the_loss_to_persist_downstream`
- `test_first_loss_jump_ignores_a_single_icmp_rate_limiting_hop`

Test coverage analysis shows `first_loss_jump` is fully covered. No further code changes were required.
