cxzg007and江俊杰 14091d21fb fix(kg): compute real relationship duration for temporal stability metric (#1143) ...

analyze_evolution() previously appended a constant placeholder (durations.append(1)) for every bounded relationship, so the stability metric was always 1.0 when any bounded relationship existed and 0 otherwise, never reflecting actual valid-time durations.

Stability now computes the mean valid-time duration in seconds ((valid_until - valid_from).total_seconds()) across relationships with both bounds set; unbounded/half-open intervals are skipped and non-positive intervals clamped to 0. Adds unit tests and a CHANGELOG entry.
