Implement a EvalGate class that can be used as a quality gate in a CI/CD pipeline:

1. run(cases: list[dict]) -> EvalGateResult — evaluate all cases and return a result object
2. Each case has: id: str, input: str, expected: str, actual: str
3. A case passes if the actual output contains all key terms from the expected output (use a simple term overlap check: at least 60% of lowercased words in expected that are longer than 3 characters must appear in actual)
4. EvalGateResult should have: passed: bool, pass_rate: float, failed_cases: list[str] (list of case IDs), total: int
5. EvalGate takes a threshold: float (default 0.85) in its constructor — passed is True if pass_rate >= threshold
6. Add a to_ci_report() -> str method on EvalGateResult that returns a human-readable summary suitable for CI log output

Write a test that demonstrates a gate passing with 9/10 cases and blocking with 8/10 cases (threshold=0.85).
