Summary

_measure_coverage: 零内容维度（如 diagram total=0）rate 从 0% 改为 1.0
_measure_coverage: overall 均分排除 total=0 的维度，避免无内容维度拉低整体覆盖率
引入 _safe_rate() 辅助函数统一处理除零边界

Root Cause

Diagram 覆盖率 0/0 被 max(len(diagram_rids), 1) 算作 0%，随后参与三
维度均分，将实际 86.1% 整体覆盖率拉低到 57.4% 并触发 70% 阈值断言失败。

Fix

Section 100% (4/4) + Table 72.2% (13/18) → Overall 86.1% ✅
Diagram 维度 0 total → rate 1.0，不参与均分

Test

pytest 全量通过 (102 passed, 13 skipped)
test_layer_b_coverage PASSED (overall 86.1%)

Closes #21

当某个维度（如图表）无内容时（total=0），rate 设为 1.0 且不参与 overall 均分。
此前 0/0 被算作 0%，将 overall 从 86.1% 拉低到 57.4%。
