Update Deptrac URL to active repository (#1429) The qossmic/deptrac repository was archived on 2026-02-17 and the project moved to deptrac/deptrac, which is actively maintained (v4.6.0 released 2026-02-02). Deptrac was originally removed from the list in PR #1402 as part of the "Remove 21 unmaintained/archived libraries" cleanup, but was re-added with the stale URL in the subsequent "tidying up" commit (bcbd70c). Point the entry at the active repository.
