M5.1：兼容键 runtimeVersion 改名 hostVersion，并限定为正整数 - #17

Conversation
M5.1。tinyui 里 runtime 已指运行时模块（tinyui-core / tinyui-native、 manifest 的 runtime 字段）与 JS 引擎，而这个值恰恰不是它们的版本，是 宿主对"给页面提供了什么"的声明。 - manifest 字段、BuildManifest、Updates 构造参数、Mismatch 枚举项、 CLI 的 --host-version、文档全部改名；文档注明即 Expo 的 runtimeVersion - 正整数校验放在 bundle、publish、releases、Updates 构造四处：App 版本 号（1.2.0）是这个名字最可能被填错的值 - 与服务端共用的签名夹具因字段改名换钥重签，Android host 与 iOS 模拟器 两端验签都过 - 文档里的"契约快照"改称 tinyui-host/<hostVersion>.txt Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

结论：批准
摘要
本次改动将热更新兼容键从 runtimeVersion 迁移为 hostVersion，并在 CLI、发布流程和 Kotlin Updates 构造处限制其为无前导零的正整数。路径、签名 manifest 字段、客户端兼容性比较及 API dump 均已同步修改。主要发现是一处更新日志将改名前后的名称写成相同值，会误导读者对协议字段迁移的理解。

<issue_to_address>
**nitpick:** The status history says the compatibility key was renamed from `hostVersion` to `hostVersion`, so it does not document the actual `runtimeVersion` → `hostVersion` migration and is misleading to readers tracking protocol changes.
**Suggested fix:** Change the history entry to say the compatibility key was renamed from `runtimeVersion` to `hostVersion`.

</issue_to_address>Sourcery assessment
Needs a human reviewer. The rename changes the signed manifest field, URL namespace, and compatibility gate used to select and persist executable update bundles; a mismatch could strand valid updates or install an update under the wrong host compatibility key. Reverting restores the code path, while already-published or installed bundles remain but can be discarded and redownloaded, so the impact is bounded and repairable.

限制“取错只会送不到”的结论。
如果 JS 构建错误地使用一个仍然存在的旧 hostVersion，包会发布到旧路径。旧宿主请求该路径后，清单中的 hostVersion 与宿主值相同，兼容性检查会通过。包可能被旧宿主安装并运行，而不是只被拒绝投递。
请将说明限定为“填写未来或不存在的值时可能送不到”。如果产品必须阻止错误宿主接收包，则需要可信的发布目标绑定，不能只依赖正整数校验。

docs/updates-plan.md的 M5.1。依赖 tiny-ui/tinyui-updates-server#2 先合并部署。为什么改名
TinyUI 里"runtime"已经有两个意思：运行时模块（
tinyui-core/tinyui-native，manifest 的runtime字段，RuntimeBundle）和 JS 引擎实例。而这个值恰恰不是它们的版本（那两者由engine/protocol管），它是宿主 App 对"给页面提供了什么"——宿主组件、宿主能力、TinyUI 版本——的声明。manifest 里runtime: [...]和runtimeVersion并排，冷读者几乎一定会读错。0.2.0 发布的代码里还没有这个名字，线上服务端也还没有任何包，此时改名只是机械替换。文档注明它就是 Expo 的
runtimeVersion。改了什么
runtimeVersion→hostVersionBuildManifest.hostVersion、Updates(hostVersion = …)、Mismatch.HOST_VERSION；API dump 同步--runtime-version→--host-version（bundle、releases）；isHostVersion导出tinyui-host/<hostVersion>.txt限定为正整数：
bundle、publish（读 manifest 时）、releases、Updates构造四处都校验，1.2.0/1.2/0/01一律拒绝，报错里点明"它不是 App 版本号"。App 版本号是这个名字最可能被填错的值，格式上直接堵住。测试
