chore(release): bump to v0.8.2 — 用量统计性能专项 + models.dev 快照同步

功能与数据口径零变化（用量数字、字段、IPC 签名、导出格式均与 v0.8.1 一致）。

- db.rs：新增进程级连接单例（含迁移只跑一次），卡片墙场景由 200+ 次「开连接 + 7 条 DDL」降为 1 次；
  新增写路径代际计数器供各处读缓存判失效
- commands.rs：load_agent_config_command 结果缓存（db 代际 + config.toml 文件戳双重校验），
  N 张供应商卡片由 N 次全量加载（config.toml 解析 + SQLite 全量读 + 逐供应商 settings 读）降为 1 次
- dashboard.rs：
  * build_all_models 单遍轻量聚合，替换原先为取一张模型表而白算日/明细/供应商三份数据的整表遍历
  * SUMMARY_CACHE 按记录集 Arc 身份 + 日期 + 分钟桶缓存热力图/模型总览/各范围汇总，切范围来回近乎零成本
  * 归档会话列表与合成记录按代际 + Arc 身份缓存（合并后的 Arc 保持稳定，否则上层缓存永不命中）
  * 解析结果持久化到 ~/.kimi-switch/scan-cache-<hash>.json：重启后首次 get_summary 直读快照
    （实测 6.4 万条记录 / 1.03 GB：22~27s → 0.85s），随后后台线程全量校验，
    有变化时经 dashboard://records-updated 事件推送，前端无感刷新（先快后准）；
    快照损坏/指纹不符静默降级为全量扫描，refresh=true 语义不变
- useDashboard.ts：stale-while-revalidate，切范围/重进页面先呈现旧数据再静默刷新，不再闪加载态；
  订阅上述事件做无感更新，保留原世代号防竞态

测试：Rust 193 项（+16）、前端 130 项全绿

+- **仪表盘重启后首次打开：约 22~27 秒 → 约 0.85 秒**（实测 6.4 万条记录 / 1.03 GB）。用量解析结果持久化到 `~/.kimi-switch/scan-cache-*.json`，启动直读快照渲染，后台线程全量校验，有变化时事件推送无感更新（先快后准）
+- **切换时间范围几乎瞬时**：热力图 / 模型总览 / 各范围汇总按记录集缓存；并去掉原「全时段」聚合的整表无用遍历
+- **界面不再闪加载态**：切范围与重进页面先呈现旧数据再静默刷新（stale-while-revalidate）
+- **供应商卡片墙变快**：供应商配置读取缓存（含外部 CLI 改动失效路径），N 张卡片由 N 次全量加载降为 1 次
+- **SQLite 连接复用**：连接与迁移改为每库一次，卡片墙场景由 200+ 次降为 1 次
+- **models.dev 快照更新**：同步至 2026-10-09（8,467 模型 / 225 供应商）
+
+## v0.8.1 (2026-10-04)
+
+- **全局配置新增两个顶层开关**：自动生成会话标题（`auto_session_title`）与重复调用拦截（`repeat_breaker`），默认开启，关闭显式写 `false`、开启删键跟随上游默认（适配 kimi-code #3962 / #3995）
+- **最大输出未匹配 models.dev 时回填默认值 131072**（128K 兜底，编辑页回填与获取模型列表预填同口径）
+- **修复 `[watch] enabled` 默认值显示**：上游 #4015 已翻回默认开启，设置页同步修正
+- **「最大输出 Token」列名精简为「最大输出」**，描述对齐上游 #4091（留空即不发送输出上限）
+
 ## v0.8.0 (2026-10-03)
 
 - **模型映射新增「最大输出 Token」列**：逐模型设置 `max_output_size`（写入 config.toml，留空用上游默认），models.dev 有 output 上限时显示可点击参考值一键填入；获取模型列表时自动预填

+# KimiSwitch v0.8.1
+
+## 新功能
+
+- **全局配置新增两个顶层开关**（适配 kimi-code 近期版本）：
+  - **自动生成会话标题**（`auto_session_title`，上游 #3962）：允许客户端自动生成会话标题，默认开启；关闭后显式写入 `false`，开启即删键跟随上游默认
+  - **重复调用拦截**（`repeat_breaker`，上游 #3995）：连续重复相同工具调用时提醒并强制停止，默认开启；可被环境变量 `KIMI_CODE_REPEAT_BREAKER` 覆盖
+- **最大输出未匹配时回填默认值 131072**（Kimi Code）：打开供应商编辑页自动回填时，models.dev 未收录的模型按 128K（131072）兜底；「获取模型列表」新增模型同口径预填
+
+## 修复
+
+- **`[watch] enabled` 默认值修正为开启**：kimi-code #4015 已把文件监听默认值翻回开启（2.0.2 曾短暂默认关闭），设置页的开关显示默认值同步修正
+- **「最大输出 Token」列名精简为「最大输出」**；列描述修正为「留空则不发送输出上限」（对齐上游 #4091：未显式配置时不发送 `max_tokens`，避免严格服务栈如 bare vLLM 报 400）

+# KimiSwitch v0.8.2
+
+本版为**性能专项**：把主要操作的等待时间从「秒级」压到「感知不到」，功能与数据口径完全不变。
+
+## 性能优化
+
+- **仪表盘重启后首次打开：约 22~27 秒 → 约 0.85 秒**（实测 1065 个 `wire.jsonl` / 1.03 GB / 6.4 万条记录）。用量解析结果持久化到本地快照（`~/.kimi-switch/scan-cache-*.json`），启动时直接读快照渲染，后台线程同时做全量校验；校验发现新记录时自动推送事件、无感更新数字（先快后准，无需手动刷新）
+- **切换时间范围几乎瞬时**：热力图、模型总览、各范围汇总结果按记录集与日期缓存，来回切换不再重复全量聚合；未命中时也不再做无用的整表遍历（原「全时段」统计会为取一张模型表而白算日/明细/供应商三份数据）
+- **界面不再闪加载态**：仪表盘切范围与重新进入页面时先呈现上次数据再后台静默刷新，不再出现数据已经拿过却先显示骨架屏的情况
+- **供应商卡片墙显著变快**：供应商配置读取结果加缓存（含敏感字段写入与外部 CLI 改动两条失效路径），N 张卡片从 N 次全量读库 + 配置解析降为 1 次
+- **SQLite 连接复用**：库连接与建表迁移从「每次调用各做一遍」改为每库一次，卡片墙场景下由 200+ 次降为 1 次
+
+## 其他
+
+- **models.dev 快照更新**：同步至 2026-10-09（8,467 模型 / 225 供应商），价格与上下文长度随之刷新
+
+## 备注
+
+- 数据口径与功能行为与 v0.8.1 完全一致：用量数字、字段、IPC 接口、导出格式均无变化；「强制刷新」仍会忽略一切缓存重新全量解析
+- 测试全量通过：Rust 193 项（新增 16 项，覆盖缓存失效、磁盘快照往返等价、损坏快照降级等）、前端 130 项
+- 首次使用本版本时会重建一次磁盘快照（沿用原有全量扫描耗时），此后每次启动均为快速加载
