v0.6.0
New opt-in AI-fix path (#1): falsegreen-skill fix <test> --case <code> --line <n> --sut <file> proposes a test-only patch for a false-green finding and PROVES it with a mutation gate (parse + behaviour-preserve + a built-in line-scoped mutation the patched test must fail on) before reporting. Propose-only - never auto-applies, never touches the SUT. V1 is Python/pytest, mechanical findings; the honest limit (proves the fix catches the targeted mutant, not every bug) is stated. See CHANGELOG.md.
