dsh-vault v0.8.6 — Round 26

✨ New features

vault_compare: field-by-field diff of two entries (onlyA / onlyB / differ / equal) — field names only, never secret values.
vault_rename: rename an entry in one call (shortcut for vault_update).
vault_search time-range filters: optional createdAfter / createdBefore (epoch millis) to filter results.
UI: vault health bar — live badges for entry/TOTP/high-sensitivity counts, rotation due, weak passwords, reused credentials, and backup age (color-coded: ok / warn / danger). Health data now actually loads (previously the report box never populated).

rotationDays: 0 now clears rotation ("never rotate") instead of keeping a zero interval that reported the entry as due forever (both on add and update).

150 tests passing (4 new: compare, rename, time-range search, rotationDays-0 clearing).

vault_compare：逐字段比较两个条目（onlyA/onlyB/differ/equal）——只返回字段名，绝不返回密钥值。
vault_rename：一次调用重命名条目（vault_update 的快捷方式）。
vault_search 时间范围过滤：新增可选 createdAfter/createdBefore（毫秒时间戳）。
UI：保险库健康栏——条目数/TOTP/高敏计数、待轮换、弱密码、复用凭据、备份天数等彩色徽章（绿/黄/红）。健康数据此前从未真正加载，现已修复并实时展示。
